Description

Model appearance updating method and device and computing equipment

Technical Field

The present disclosure relates to the field of computer technologies, and in particular, to a method and an apparatus for updating model appearance, and a computing device.

Background

With the continuous development of the simulation technology of the computer, in order to intuitively display entity devices including a server, a memory, a switch, a cabinet and the like on the computer, a three-dimensional model of the simulated entity device can be displayed on the computer by creating the three-dimensional model of the entity device.

Currently, after the three-dimensional model of the simulation entity device is created, if the appearance of a certain part in the three-dimensional model needs to be adjusted, the three-dimensional model needs to be remodelled, and the remodelling process comprises the steps of modifying a model skeleton, adding a model map, adding codes and the like. For example, if it is necessary to add a color block of an indicator light to an indicator light region simulated on a three-dimensional model of a simulated hard disk that has been created and displayed in a web page, it is necessary to re-model the three-dimensional model of the simulated hard disk by modeling software and then reissue. This results in a cumbersome step of updating the appearance of the model.

In the related art, since the three-dimensional model needs to be remodelled with more modifications, the implementation period of the model appearance update is longer, so that the model appearance update efficiency is lower.

Disclosure of Invention

The embodiment of the application provides a model appearance updating method, device and computing equipment, which simplify the operation of updating the appearance of a three-dimensional model and further improve the model appearance updating efficiency.

In a first aspect, the present application provides a method for updating a model appearance, the method including: displaying a first model, wherein the first model is a three-dimensional model with a first texture appearance generated according to first texture map rendering; in response to receiving a triggering operation on a first position, determining a first coordinate of a target position, wherein the first position is a corresponding position of the first model displayed on a display interface, the target position is a position of the first position mapped on the surface of the first model, and the first coordinate of the target position is a three-dimensional coordinate of the target position in a three-dimensional space in which the first model is located; determining a second coordinate of the target position based on the first coordinate of the target position, wherein the second coordinate of the target position is a two-dimensional coordinate of the first coordinate of the target position mapped on a two-dimensional space where the first texture map is located; the appearance of the first model is updated based on the second coordinates of the target location and the second texture map.

It will be appreciated that by performing a triggering operation on a corresponding first position on the displayed first model, a first coordinate of a target position of the first position mapped on the three-dimensional model surface may be determined, a second coordinate of the target position mapped on a two-dimensional space where the first texture map is located may be determined according to the first coordinate of the target position, and updating of the appearance of the first model may be determined to be achieved according to the second coordinate. That is, by acquiring the position where the trigger operation is performed on the first model, the area where the second texture map needs to be displayed on the first model can be determined, the three-dimensional problem of changing the appearance of the three-dimensional model is changed into the two-dimensional problem of modifying the mapping texture map, the three-dimensional modeling can be omitted on the basis of displaying the three-dimensional model by reducing the dimension of the coordinates of the target position, and the appearance of the three-dimensional model is updated in a manner of directly displaying the texture map on the three-dimensional model according to the target position, so that the operation of updating the appearance of the three-dimensional model is simplified, and the efficiency of updating the appearance of the model is improved.

In one possible implementation, updating the appearance of the first model based on the second coordinates of the target location and the second texture map includes: determining a target area based on the second coordinates of the target position; the second texture map is superimposed on the target area of the first texture map to update the appearance of the first model.

It will be appreciated that updating the appearance of the model may be achieved by determining the region on the first model where the second texture map needs to be superimposed, and superimposing the second texture map on the first texture map of that region.

In one possible implementation, the target region is a pixel on the first texture map that contains the second coordinates of the target location and conforms to the size and shape of the preset two-dimensional graphic.

It can be understood that, if the preset two-dimensional pattern is provided, after the second coordinate of the target position is obtained, the area which contains the pixel point of the second coordinate and accords with the size and shape of the preset two-dimensional pattern can be determined as the target area according to the size and shape of the preset two-dimensional pattern. And the second texture map can be superimposed on the first texture map according to the size and the shape of the preset two-dimensional graph, so that the accuracy of model appearance updating is improved.

In one possible implementation, the target region is a region on the first texture map that is the same color as the pixel at the second coordinate of the target location or within a specified interval as the color error of the pixel at the second coordinate of the target location.

It can be understood that the region with the same color or color error in the designated interval is determined as the target region according to the color of the pixel point at the target position on the first model, so that the position region on the first texture map, which needs to be overlapped with the second texture map, can be accurately determined, and the accuracy of updating the appearance of the model is improved.

In one possible implementation, the method further includes: in response to receiving a trigger operation on the second position, determining a third coordinate of a third position, wherein the second position is a position of the first model, which is displayed on the display interface, except for other corresponding positions of the first position, and the third position is a position of the second position mapped on the surface of the first model, and the third coordinate of the third position is a three-dimensional coordinate of the third position in a three-dimensional space where the first model is located; determining a fourth coordinate of the third position based on the third coordinate of the third position, wherein the fourth coordinate of the third position is a two-dimensional coordinate of the third position mapped on a two-dimensional space where the first texture map is located; superposing the second texture map at a position corresponding to the fourth coordinate of the first texture map; and updating the appearance of the first model according to the second texture map.

It can be understood that by performing the triggering operation on the second position except the first position on the surface of the first model, the third coordinate of the third position corresponding to the second position can be obtained, and the second texture maps are overlapped on the corresponding position on the first texture maps based on the third coordinate, so that the second texture maps are overlapped on the corresponding position of each first texture map after the triggering operation is performed on each second position in batches, the appearance of the first model is updated according to the overlapped second texture maps, the operation of performing appearance updating on a plurality of positions of the first model is simplified, the model appearance updating operation for performing the batch is realized, and the model appearance updating efficiency is improved.

In one possible implementation, updating the appearance of the first model based on the second coordinates of the target location and the second texture map includes: superposing the second texture map at a position corresponding to the second coordinate of the first texture map corresponding to the target position to generate a third texture map; and updating the appearance of the first model according to the third texture map.

It will be appreciated that the first texture of the corresponding location on the first texture map is replaced with the second texture of the second texture map based on the second coordinates of the target location, a third texture map is generated, and the appearance of the first model is updated in accordance with the third texture map. So that an appearance update of the first model can be achieved.

In one possible implementation, the method further includes: determining a first state of the second texture map, the first state being used to indicate that the second texture map is displayed or hidden; and in response to receiving the preview trigger operation, displaying the appearance of the updated first model in the first state.

It will be appreciated that after determining that the second texture map is displayed or hidden, if a preview trigger operation is received for the first model, the second texture map may be displayed or hidden, thereby enabling an update to the appearance of the first model.

In one possible implementation, determining the first state of the second texture map includes:

and determining the first state of the second texture map according to the state switching frequency, wherein the state switching frequency is the frequency of switching the display state and the hidden state of the second texture map.

It can be appreciated that the second texture map of the target object is switched between the display state and the hidden state according to the state switching frequency, so that the updated first model can be dynamically displayed.

In one possible implementation, the first model is a model for simulating the first device and the second texture map is an indicator light map for prompting an operational state of the first device.

It can be understood that in one case, the first model may be a model for simulating the first device, and the second texture map may be an indicator light map for prompting the running state of the first device, so that the addition of the indicator light map to the model for simulating the first device is realized, and the simulation effect of the model is improved.

In one possible implementation, the method further includes: acquiring the running state of first equipment; determining a first state of the indicator light map at the current moment based on the operation state of the first equipment; the first state is used for indicating the indication lamp to be mapped and displayed or hidden; and updating the appearance of the first model according to the first state of the indicator light map so as to simulate the operation state of the first equipment indicated by the indicator light.

It can be understood that whether the current time indicator light map is in a display state or in a hidden state is determined by acquiring the running state of the first device, so that a model simulating the first device can dynamically display the indicator light map according to the actual running state of the first device, the simulated indicator light can indicate the running state of the first device, and the simulation effect of the model is improved.

In one possible implementation, the method further includes: generating a webpage package; the webpage package comprises a model framework of the first model and a texture map of the first model after appearance updating, and is used for downloading by other devices.

It will be appreciated by those of skill in the art that the words "first," "second," and the like do not limit the amount and order of execution, and that the words "first," "second," and the like do not necessarily differ. Meanwhile, in the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as examples, illustrations, or descriptions. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion that may be readily understood.

First, an application scenario of the embodiment of the present application is described in an exemplary manner.

Currently, in digital twin systems for internet technology (internet technology, IT) devices, most of the digital twin systems display three-dimensional models of the IT devices such as servers, memories, switches or cabinets, and the displayed three-dimensional models usually do not include details (such as indicator lights), so that the displayed three-dimensional models can be used for viewing the general appearance of the IT devices on a subscriber line. The efficiency of operation and maintenance management of IT equipment cannot be improved.

The digital twin can be a simulation process integrating multiple disciplines, multiple physical quantities, multiple scales and multiple probabilities by fully utilizing data such as a physical model, sensor update and operation history, and mapping is completed in a virtual space, so that a full life cycle process of corresponding entity equipment is reflected. Digital twinning is a beyond-the-reality concept that can be seen as a digital mapping system of one or more important, mutually dependent equipment systems. A digital twin may be a digital version of a "clone" created on the basis of a device or system, and may include a virtual representation of the real world of physical objects, processes, relationships, behaviors, and the like. The digital twin skeleton may be the geometry of each digital twin in the digital twin system. In geometry, a finite body surrounded by a plurality of geometric surfaces (plane or curved surface) can be called a geometric body, a surface surrounding the geometric body is called an interface or a surface of the geometric body, intersecting lines of different interfaces are called edge lines of the geometric body, intersecting points of different edge lines are called vertexes of the geometric body, and the geometric body can also be regarded as a finite space area divided by a plurality of geometric surfaces in space. A material may represent a surface property of the rendered geometry, including the color used, and the degree of brightness, a material may reference one or more textures that may be used to wrap an image onto the surface of the geometry. Textures may generally represent an image that is loaded from a file, generated on a canvas, or rendered from another scene. In a digital twin system, the texture may be composed of one or more poster files due to the relatively high realism, and the texture in a digital twin system may be referred to as a digital twin texture map.

In the related art, a digital twin, i.e., a three-dimensional model of an IT device is presented in a digital twin system, including only the appearance of a fixed display of the IT device, which may refer to the model appearance of an analog IT device that is not affected by the operational state of the IT device.

That is, an indicator light or other indicating component for indicating the operational status of the IT device is not included on the three-dimensional model of the IT device displayed in the digital twinning system.

Since indicator lights are an important reference for IT devices such as servers, memories, switches to determine fault conditions. Serial attached small computer system interface (serial attached small computer system interface, SAS)/serial advanced technology attachment (serial advanced technology attachment, SATA) hard disk is exemplified herein. The SAS/SATA hard disk has two kinds of indicator lamps, one is a fault indicator lamp, which can be mainly used for prompting the fault occurrence, and the other is an active indicator lamp, which can be mainly used for displaying the normal working condition of the hard disk. In order to make the digital twinning system more realistic, the design of the digital twinning system is met, and the display of the indicator lamp needs to be added in the digital twinning system. If the display of the indicator lamp is needed to be added in the digital twin system, the user is needed to modify the three-dimensional model of the IT equipment again manually, and the position of the indicator lamp is modeled again.

In view of this, the following embodiments of the present application provide a method for updating the appearance of a model, which can further implement adding a texture map according to a position where a trigger operation is received when a user performs a trigger operation on a certain position on a three-dimensional model of an IT device on the basis of displaying the three-dimensional model of the IT device in a digital twin system according to a related technology, so as to avoid remodelling the three-dimensional model of the IT device.

Next, an exemplary description is given of a system architecture of an embodiment of the present application.

That is, the computing device 100 may run a three.js engine and support Web graphic library (Web graphics library, webGL) technology, web three-dimensional (Web 3D) technology.

Among other things, webGL is a technology that renders interactive 2D and 3D graphics in any compatible web browser without the use of plug-ins.

It should be noted that, the system architecture and the application scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the system architecture and the appearance of a new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

For ease of understanding, the model appearance updating method provided in the present application is described below by way of example with reference to the accompanying drawings, and is applicable to the computing device shown in fig. 1.

Fig. 2 is a flow chart illustrating a method for updating a model appearance according to an exemplary embodiment of the present application. The model appearance updating method comprises the following steps:

S101, displaying the first model.

Wherein the first model is a three-dimensional model generated in accordance with a first texture map, which is a pattern mapped for display on the first model, the first texture map may include at least one of a motif, a pattern, or a color.

In one possible implementation, the computing device may display the first model via an external display device.

The computing device displays a digital twin system manufacturing platform interface through the display device, and displays a first model on the digital twin system manufacturing platform interface.

Illustratively, a user may open a pre-created first model by logging into the digital twinning system production platform and displaying the first model on the digital twinning system production platform interface, e.g., fig. 3 is a schematic diagram of a digital twinning system production platform interface according to an embodiment of the present application. As shown in fig. 3, the digital twinning system production platform 200 may have a first model 201 displayed therein, and the first model 201 may be a three-dimensional model simulating a server.

S102, determining first coordinates of a target position in response to receiving a triggering operation on a first position, wherein the first position is a corresponding position of a first model displayed on a display interface, and the target position is a position of the first position mapped on the surface of the first model.

The first position is a corresponding position of the first model displayed on the display interface, the target position is a position of the first position mapped on the surface of the first model, and the first coordinate of the target position is a three-dimensional coordinate of the target position in a three-dimensional space where the first model is located. The target location may be any location on the first model, and the first location may be determined by a user selecting and triggering a certain location point on the first model displayed on the display interface.

For example, if the first model is displayed through an external display device of the computer device, the user may select and trigger a certain position point on the first model on the display interface by means of clicking a mouse; if the first model is displayed through the computing device with the touch screen, the user can click on the touch screen in a manual triggering mode, so that the position point displayed on the display interface of the first model is selected and triggered.

Illustratively, fig. 4 is a schematic diagram of determining a target position on the first model according to an embodiment of the present application, and as shown in fig. 4, when a user performs a triggering operation on a displayed position point 202 on the first model, it may be determined that the target position on the first model is the position point 202.

Because each position point on the first model can be clicked and triggered, the user can select and trigger any position on the first model, and the position of the target position on the first model is not limited.

In one possible implementation manner, when the computing device receives a triggering operation on the target position on the first model, firstly, two-dimensional coordinates of a position point of the triggered first position on the display interface can be determined, then, as a space rectangular coordinate system is preset in the first model, namely, a three-dimensional space in which the three-dimensional model is located, each point on the first model has corresponding three-dimensional coordinates, a camera is also present in the three-dimensional space except for the first model, the position coordinates of the camera are the three-dimensional coordinates determined in the space rectangular coordinate system, and the computing device acquires the position coordinates of the camera; then, according to the two-dimensional coordinates of the position point of the first position on the display interface, the three-dimensional coordinates of the first position in the three-dimensional space (the first space rectangular coordinate system) where the three-dimensional model is located can be determined, the computing device can determine a ray through the three-dimensional coordinates of the position point on the first model corresponding to the camera coordinates and the first position in the three-dimensional space, the ray can be obtained through connecting a position point indicated by the camera coordinates with a position point on the first model corresponding to the first position, the intersection point of the ray and the first model is determined to be a target position, and the first coordinate of the target position is determined through acquiring skeleton information of the position point in the three-dimensional space. It is understood that the target location is the location of the first location map on the first model surface.

Wherein the image of the first model taken at the camera position is an image displayed on the display interface, and the skeleton information of the position point in the three-dimensional space may indicate the geometry in which the position point is located, including information of a point, a line or a plane.

Fig. 5 is a schematic perspective view of an embodiment of the present application. As shown in fig. 5, the image on the near clipping plane 302 is an image obtained by capturing a three-dimensional model in space with a camera 301, and according to the projection mapping relationship between the near clipping plane 302 and the far clipping plane 303, the position point 304 of the determined target position on the display interface is projected onto the three-dimensional model in three-dimensional space, and may correspond to the position point 305 of the first position on the three-dimensional space.

Specifically, determining the three-dimensional coordinate of the first position in the three-dimensional space (the first space rectangular coordinate system) in which the three-dimensional model is located according to the two-dimensional coordinate of the first position may include: based on the planar rectangular coordinate system of the two-dimensional plane where the near clipping plane (display interface) 302 is located, a second spatial rectangular coordinate system where the display interface 302 is located is first established. For example, the x-axis and the y-axis of the planar rectangular coordinate system are defined as the x-axis and the y-axis of the second spatial rectangular coordinate system, a straight line passing through the origin of the planar rectangular coordinate system and perpendicular to the x-axis and the y-axis is defined as the z-axis. And then determining the three-dimensional coordinates of the camera position of the three-dimensional model in a second space rectangular coordinate system. And finally, determining a coordinate first corresponding relation between the first space rectangular coordinate system and the second space rectangular coordinate system according to the three-dimensional coordinates of the camera position of the three-dimensional model in the first space rectangular coordinate system and the three-dimensional coordinates of the camera position of the three-dimensional model in the second space rectangular coordinate system. Based on the coordinate correspondence, the three-dimensional coordinates of the first position in the first space rectangular coordinate system are determined according to the three-dimensional coordinates of the first position in the second space rectangular coordinate system. The first space rectangular coordinate system is the space rectangular coordinate system where the three-dimensional model (first model) is located.

For example, the two-dimensional coordinates of the first position are (x, y), the three-dimensional coordinates of the first position in the second space rectangular coordinate system are (x, y, z), the three-dimensional coordinates of the first position in the first space rectangular coordinate system are (x 1, y1, z 1), and the coordinates of the first space rectangular coordinate system and the second space rectangular coordinate system correspond to each other as follows:

x1＝x*2+1；

y2＝y*2+1；

z1＝z；

and the three-dimensional coordinates of the first position in the second space rectangular coordinate system are (1, 1), and the three-dimensional coordinates of the first position in the first space rectangular coordinate system can be determined to be (3, 1) according to the coordinate corresponding relation between the first space rectangular coordinate system and the second space rectangular coordinate system.

Therefore, the three-dimensional coordinate of the first position in the first space rectangular coordinate system can be determined according to the coordinate correspondence relationship between the first space rectangular coordinate system and the second space rectangular coordinate system, the first ray can be determined according to the three-dimensional coordinate point and the coordinate point of the camera position in the first space rectangular coordinate system, the coordinate of the intersection point is obtained through the intersection point (target position) of the first ray and the outer surface of the three-dimensional model through the API of the thread.

In one possible implementation, if the first ray intersects the first model, and there are 2 intersections, the computing device may take as the target location the intersection closest to the mouse click point.

For example, first, the computing device may obtain camera coordinates of a camera in a three-dimensional space in which the three-dimensional model is located, and obtain two-dimensional coordinates of a position point of a first position clicked by a user in a two-dimensional space of a display interface; the user clicks the screen, and the web page acquires the point coordinates of the screen through a mouse click event (S _x ,S _y ) The point coordinates are calculated by normalization (S _x ,S _y ) And converting the first position into two-dimensional coordinates (x, y) of the first position in a two-dimensional space of the display interface.

S103, determining second coordinates of the target position based on the first coordinates of the target position.

The second coordinate of the target position is a two-dimensional coordinate of the first coordinate of the target position mapped on a two-dimensional space where the first texture map is located.

In one possible implementation, the computing device determines, by the acquired first coordinates of the target location, a location point on the first texture map corresponding to the first coordinates when the first texture map is overlaid on the model skeleton of the first model, and determines, as the second coordinates, two-dimensional coordinates of the location point on the first texture map.

The manner of determining the second coordinate of the target position according to the first coordinate of the target position may be a texture map UV mapping method. The first texture map may be regarded as a two-dimensional image tiled on a desktop, the left-right direction of the two-dimensional image is taken as a U-axis, the up-down direction of the two-dimensional image is taken as a V-axis, a plane formed by the U-axis and the V-axis may be taken as a texture space coordinate system, and the first texture map is superimposed on a model skeleton of the first model to achieve the purpose of adding texture to the appearance of the first model. Thus, the first coordinate of the target position may be converted into the second coordinate of the target position by means of UV mapping, thereby determining the position point on the first texture map indicated by the second coordinate.

Illustratively, fig. 6 is a schematic diagram of a texture map UV mapping process according to an embodiment of the present application, as shown in fig. 6, an exemplary texture map 51 may be regarded as a two-dimensional image tiled on a desktop, and the purpose of adding texture to the exemplary model 52 may be achieved by overlaying the exemplary texture map on the model skeleton of the exemplary model 52.

S104, determining a target area based on the second coordinates of the target position.

In this embodiment of the present application, after determining the second coordinate of the target position, the computing device may determine, according to the second coordinate, an area on the first model that needs to be superimposed on the second texture map, and use the area as the target area.

Wherein the target region is used to indicate a region on the first model that overlays the second texture map. The second texture map may be a pre-configured texture map, for example, a map of the same color.

In one possible implementation, the target region may be a region on the first model that includes pixels of the second coordinates of the target location and conforms to the shape and size of the preset two-dimensional graph.

That is, before determining the target object, the computing device may acquire a preset two-dimensional pattern, and determine a shape and size area that includes the pixel point of the second coordinate of the target position and conforms to the preset two-dimensional pattern as the target area.

The preset two-dimensional graph can be a preset two-dimensional graph or a two-dimensional graph selected by a user. The preset two-dimensional pattern may be a regular pattern, such as square, circular, oval, etc.; or may be an irregular pattern, such as a custom pattern that is selected by a user to preset the shape and size of a two-dimensional pattern or to draw.

Fig. 7 is a schematic diagram illustrating selection of a preset two-dimensional graph, as shown in fig. 7, after a user logs in a digital twin system manufacturing platform, a selection pop-up 401 for selecting the preset two-dimensional graph may be displayed in a pop-up form, and in the selection pop-up 401, a shape of a map to be added on the first model may be selected through a mouse pointer trigger operation of the user, for example, if the two-dimensional graph is selected to be square, a square map may be added when the map is added later.

For example, if the first model is a model for simulating the first device and the second texture map is an indicator map for prompting an operation state of the first device, it may be determined that the target area is an area including the target position, which needs to be added with an indicator on the first model, and is a preset two-dimensional graphic shape.

In one possible implementation, the target region may also be a region on the first model that contains the target pixel, where the color on the target pixel is a first color or a color within a specified interval from the first color, which may be the color of the pixel at the second coordinate of the target location on the first texture map.

That is, prior to determining the target region, the computing device may obtain a first color of the pixel points at the second coordinates of the target location on the first texture map and determine each target pixel point that is the same as the first color or has a color error within a specified interval within a specified threshold distance around the second coordinates on the first texture map, and determine the region on the first model that includes each target pixel point as the target region.

The computing device may find pixels with the same or similar color as the pixels of the second coordinate of the target location on the first texture map according to the second coordinate of the target location, until pixels with different colors are encountered as the pixels of the boundary of the target object.

In addition, if the target area also accords with the preset two-dimensional graph of the target area, the preset two-dimensional graph can be taken as a diffusion direction, and finally, an area, the pixel color of which is the same as that of the pixel at the target position and accords with the preset two-dimensional graph, can be determined as the target area.

That is, according to the second coordinates of the target position on the first texture map and the preset two-dimensional pattern, a small preset pattern (for example, square) may be formed first, the computing device may determine whether the color of the pixels on the outer layer of the preset pattern is the same as the color of the pixels in the preset pattern, and if so, expand the outer layer until expanding to the boundary with different colors of the pixels.

For example, if the first model is a model for simulating the first device, the second texture map is an indicator light map for prompting the operation state of the first device, and since the color of the pixels corresponding to the position where the indicator light needs to be added on the first texture map of the first model is different from that of other regions, the region where the indicator light needs to be added on the first texture map can be determined as the target region by looking for the region where the pixels on the first texture map are the same by out-diffusing with the second coordinate of the target position, and the first texture map superimposed by the target region is the region reserved by the developer for adding the indicator light map. As shown in fig. 3, the square area with black on the first model 201 may be an area reserved on the first texture map during modeling, if the target position is in the reserved area, an area with black color is found by outward diffusion at a position corresponding to the second coordinate based on the target position, and until pixel points with different colors are encountered as boundaries, it may be determined that the target area is a black reserved area including the target position.

S105, updating the appearance of the first model according to the target area and the second texture mapping.

In the embodiment of the application, after the target area is determined, the second texture map may be displayed in an overlaid manner on the target area, so as to display the appearance of the updated first model.

The shape, position and size of the second texture map superimposed on the first model may be fine-tuned, i.e. the shape, position and size of the second texture map superimposed on the first model may be adjusted by a user through operations such as dragging, scaling, etc.

For example, if the first model is a model for simulating the first device, the second texture map is an indicator light map for prompting the operation state of the first device, and the color of the second texture map may be preset, or may be reset after the user fine-tunes the superimposed second texture map.

That is, after the computing device automatically determines the shape size of the added indicator light map, the user may determine whether the shape size of the generated indicator light map meets the expectations, and if not, the user may modify the shape size and even the position of the indicator light map by triggering an operation.

Alternatively, in another possible implementation manner, the appearance updating of the first model may further generate a third texture map according to the first texture map, the position of the second coordinate, and the second texture map, where the third texture map is a texture map generated by stitching after superimposing the second texture map with the determined shape size at the target position on the first texture map at the position of the second coordinate, and the appearance of the first model is updated according to the third texture map, and in particular, S103 to S105 may be replaced by the following steps S106 to S107:

S106, the computing device superimposes the second texture map of the target area at a position corresponding to the second coordinate of the first texture map corresponding to the target position, and generates a third texture map.

S107, the computing device updates the appearance of the first model according to the third texture map of the target area.

In a possible case, after the second texture map is superimposed on the target area corresponding to the target position, since the shape and the content of the superimposed second texture map are already determined, the second texture map with the shape and the content adjusted for the object corresponding to the other position can be further superimposed, so that the operation of adding the map can be performed in batches, and the efficiency of adding the map on the first model can be improved, and specifically the method includes the following steps:

s11, determining a third coordinate of a third position in response to receiving the triggering operation of the second position.

The second position is the corresponding position of the first model, except the first position, displayed on the display interface, the third position is the position of the second position mapped on the surface of the first model, and the third coordinate of the third position is the three-dimensional coordinate of the third position in the three-dimensional space where the first model is located.

In one possible implementation, when the computing device receives a trigger operation for a second location on the first model other than the first location, the three-dimensional coordinates of the second location mapped in the first spatial rectangular coordinate system in which the first model is located may be determined according to the two-dimensional coordinates of the second location in the display interface.

The specific determination manner of the third coordinate of the third position is the same as that of the first coordinate of the target position, as shown in S102, which is not described herein.

S12, determining fourth coordinates of the third position based on the third coordinates of the third position.

The fourth coordinate of the third position is a two-dimensional coordinate of the third position mapped on the two-dimensional space where the first texture map is located.

The specific manner of determining the fourth coordinate of the third position by the computing device through the third coordinate of the third position is the same as the manner of determining the second coordinate of the target position by the first coordinate of the target position, as shown in S103, which is not described herein.

And S13, superposing the second texture map at a position corresponding to a fourth coordinate of the first texture map corresponding to the third position.

Wherein, since the target region has been determined, the shape and content (color, size, etc.) of the second texture map superimposed on the first model has been determined, the computing device may superimpose the second texture map of the determined shape, content at a location corresponding to a fourth coordinate of the first texture map corresponding to the third location.

And S14, updating the appearance of the first model according to the second texture map and the superposition position of the second texture map.

Wherein, after the computing device superimposes the second texture map of the target area at the position of the first texture map indicated by the fourth coordinate of the third position, the same map as that at the target position is added at other positions of the first model can be displayed on the display interface, and at this time, the user can fine-tune the texture maps at the other positions as well so as to achieve that the appearance of the updated first model meets the expectations.

For example, as shown in fig. 3, a batch application control may be displayed on the digital twin system production platform 200, after a user adds a texture map to a target location, a trigger operation may be performed on the batch application control, and after receiving the trigger operation on the batch application control, the computing device may start a function of acquiring other locations, that is, when the user performs a trigger operation on other locations except for the target location on the first model, the same texture map as that at the target location may be added at each other location.

If the user completes the online updating process of the first model, that is, after adding the texture map to the first model, the appearance of the online updated first model may be displayed, and the specific displaying process may be as follows:

S21, determining a first state of a second texture map of the target area.

Wherein the first state may be used to indicate that the second texture map of the target region is displayed or hidden.

That is, after overlaying the second texture map on the target region, or when the computing device receives a preview trigger operation, a respective first state of at least one second texture map added on the first model at that time is determined. In one possible implementation, the computing device may determine the first state of the second texture map according to a state switching frequency, which is a frequency at which the display state and the hidden state of the second texture map are switched.

The state switching frequency may be a preset parameter, or may be a parameter set by the user for each of the at least one second texture map before the preview is performed.

That is, if the state switching frequency is preset once per second, the computing device may display the default state after receiving the preview triggering operation, and if the default state is the hidden state, hide each second texture map added on the first model, and then switch the state of each second texture map once per second according to the preset state switching frequency, so as to achieve the effect of flashing once per second.

Or if the user sets the parameters for each of the at least one second texture map before previewing, the user may identify each of the at least one second texture map added on the first model by numbering and set each of the state switching frequencies according to the numbers, and after the user sets and after the computing device receives the preview triggering operation, each of the second texture maps may be displayed or hidden according to the state switching frequency corresponding to each of the numbers.

For example, if the state switching frequency is set to be switched once every second for the second texture map with the number 1 and the state switching frequency is set to be switched once every two seconds for the second texture map with the number 2, the state switching of the second texture maps can be performed according to the state switching frequency set in advance, so that the effect that the second texture map with the number 1 blinks once every second and the second texture map with the number 2 blinks once every two seconds is achieved.

In another possible implementation manner, if the first model is a model for simulating the first device, the second texture map is an indicator light map for prompting an operation state of the first device, and since the blinking state of the indicator light map may represent the operation state of the first device, in order to enable the first model to simulate the operation state of the first device through the added blinking state of the indicator light map, the computing device may acquire the operation state of the first device, and determine the first state of the indicator light map at the current moment based on the operation state of the first device; and displaying the appearance of the updated first model according to the content of the indicator light map of the target area and the first state of the indicator light map so as to simulate the operation state of the first equipment indicated by the indicator light.

For example, if the first model is used for simulating an SAS/SATA hard disk, the second texture map is an indicator light map, and since two indicator lights are present on the SAS/SATA hard disk, one is a fault (fault) indicator light, which can be mainly used for prompting the fault occurrence condition, and the other is an active (active) indicator light, which can be mainly used for displaying the normal working condition of the hard disk; when the active indicator lamp is green and normally on and the fault indicator lamp is off, the hard disk can be indicated to work normally; when the active indicator lights flash green and the fault indicator lights are turned off, the hard disk can be used for reading and writing data; when the active indicator lights are green and normally bright or green blinks, and the fault (fault) indicator lights are yellow blinks, the hard disk can be indicated to be positioned or RAID reconstruction is performed; when the active indicator light is green and normally on or off and the fault (fault) indicator light is yellow and normally on, the fault of the hard disk can be indicated; when the active indicator lights are turned off and the fault indicator lights are also turned off, it may be indicated that the hard disk is out of place or that the hard disk is faulty. The operating state of the real device (SAS/SATA hard disk) can be characterized by controlling the display or hidden state of the indicator map. The first state may be used for indicating that the indicator light map of the target area is displayed or hidden.

Wherein, in the case that the computing device automatically generates the indicator map and the user determines that the shape size and position of the indicator map need not be modified, the user may set the indicator map to a number (such as Fault-1), and write a custom script for the status switching frequency of the indicator map, where the custom script includes a function for determining the status switching frequency according to the operation status of the first device.

S22, displaying the updated first model according to the second texture map and the first state of the target area.

Wherein the computing device may dynamically display the updated first model in accordance with the second texture map of the target region and the determined first state at the current time.

In one possible case, the computing device may generate a web page package; the webpage package can comprise a model skeleton of the first model, a first texture map and a second texture map of a target area overlapped on the first texture map, and the webpage package can be used for downloading by other devices.

For example, if other devices download the above-mentioned webpage package, the other devices may load the webpage package and read the three-dimensional information of the first model provided in the webpage package, and load all model skeletons and texture maps in the digital twin system in the webpage package by loading a three.js 3D engine, when all model skeletons and texture maps are loaded, the indicator lamp texture maps generated by the previous platform may be in a hidden stage. Therefore, in the webpage seen by the current user, the indicator lamps are in a non-bright state, after loading is completed, according to the previously set frequency or frequency function, the indicator lamp mapping is switched between a display state and a hidden state, so that the indicator lamps show a flickering effect, or the indicator lamp mapping is continuously displayed and hidden according to the specified frequency or the frequency of changing the operation data of the actual equipment transmitted back by the background. At this time, the user can observe that the analog device indicator lamp in the webpage flashes according to the real state.
