Description

  The present invention relates to a bar arrangement verification support device that contributes to improvement of work efficiency in bar arrangement verification work for detecting interference of reinforcing bars generated in connecting parts of various frames such as columns and beams constituting a building before construction, and Regarding the program.

The building has a connecting portion formed by connecting a plurality of housings from different directions to one housing.
In each connecting portion, the reinforcing bars of the mutually connected casings are intertwined in a complex manner while maintaining the coupling strength between the continuous casings.
Conventionally, reinforcing bars that are intertwined in such a complicated manner are automatically corrected by a system described in Patent Documents 1 to 4 below, for example, so that interference between the reinforcing bars is eliminated, The placement was decided.

However, due to the recent policy to strengthen earthquake resistance, the amount of reinforcing bars that make up the frame has increased, and the situation of interference between the reinforcing bars arranged in the frame has become more complex. .
As a result, in buildings designed based on desk-top structural calculations, there are many cases where reinforcement cannot actually be physically made, and interference between reinforcing bars cannot be avoided by structural calculations alone. It became.
Therefore, in order to avoid such a current situation, it has been forced to carry out strict bar arrangement verification work by hand before construction on site.

  Conventionally, when performing such bar arrangement verification work, the connecting part of the floor plan is enlarged, and an image (hereinafter referred to as “two”) representing the arrangement of the reinforcing bars (which may include a frame shape). This is displayed on a display screen as a “dimensional image”), and the two-dimensional image is observed in detail from the top, bottom, left, and right, thereby confirming the interference state of the reinforcing bars disposed in the connecting portion.

JP 2009-30403 A JP 2013-125383 A JP 2014-14143 A JP 2014-109933 A Japanese Patent Laid-Open No. 7-230469 JP 2001-123664 A JP2013-84040A

However, in the above-described conventional method, when the connecting portion for verifying the bar arrangement state is displayed on the display screen, the adjacent frame or connecting portion is displayed in front of the connecting portion to be verified. Therefore, there is a problem that it is not possible to clearly observe only the target bar arrangement state.
In addition, only in the two-dimensional image, it is not possible to clearly recognize in what use many rebars are emitted from which housing or in what form (hereinafter referred to as “role etc.”), In addition, there is a problem that it is not easy to confirm it with reference to another image.
On the other hand, if the connection part is to be cut out, complicated work is involved in setting the space to be cut out, and each casing constituting the connection part is to be cut in a plane with the body axis as the normal line. If this is done, more difficult work will be involved.

  The present invention has been made in view of the above circumstances, and the arrangement of the verification points is not concealed in the adjacent frame or connecting portion, and the arrangement of the reinforcing bars can be efficiently performed while confirming the role of each reinforcement. It is an object of the present invention to provide a bar arrangement verification support apparatus capable of performing a muscle state verification operation and a program thereof.

  A bar arrangement verification support apparatus according to the present invention, which has been made to solve the above-described problems, includes a designation unit that detects a frame to be a bar arrangement examination target from the coordinates of a screen on which a point operation has been performed, and a rod detected by the designation unit A connecting housing specifying means for detecting a housing to be connected to, a connecting portion cutting means for cutting out a connecting portion made of the housing detected by the specifying means and the connecting housing specifying means, and the connection cut out by the connecting portion cutting means Support image creating means for displaying the external appearance of the part.

In order to make the cut surface of the connecting portion perpendicular to the frame axis, the bar arrangement verification support device cuts the frame detected by the designation unit and the connection frame specifying unit along a plane whose normal is the frame axis. It can be set as the structure provided with the said connection part cutting-out means.
In addition, a means for creating a projection plane whose normal is the rod axis of the frame constituting the connecting portion cut out by the connecting portion cutting means, and the projection lines of the skin of the rod and the rebar of the reinforcing bar after the hidden line processing are described above. It can also be configured as a bar arrangement verification support device comprising the support image creation means having means for projecting onto the projection plane.

  The support image creating means may be configured to display a cut surface of the connecting portion and appropriately display a two-dimensional image or a three-dimensional image in which the appearance of the connecting portion is viewed from various angles. Here, the three-dimensional image is an image that three-dimensionally represents the arrangement of reinforcing bars (which may include a frame shape).

As a configuration that can appropriately change the display direction of the appearance of the connecting portion, for example, a line-of-sight change that changes a line of sight that displays the connecting portion cut out by the connecting portion cutting means according to the starting point, direction, and amount of the drag operation. It can also be configured as a bar arrangement verification support device comprising means.
The reference point may be the rotation center itself when changing the line of sight, or may be a point serving as a basis for determining the center of the line of sight change.

  The present invention made to solve the above problems can also be configured as a bar arrangement verification support program that causes a computer to function as the bar arrangement verification support device.

  In addition, it is possible to display a multi-dimensional display of the appearance of the connection part currently being verified and the state of bar arrangement, a three-dimensional image close to the actual bar arrangement state, and a two-dimensional image that can accurately verify the arrangement of reinforcing bars in a plane. By configuring, it is possible not only to intuitively verify the state of interference between reinforcing bars in the frame during or after correction, but also to check the role of each reinforcing bar, etc. And can be verified accurately.

  In addition, even in the case of performing extremely complicated work of accurately writing the bar arrangement state to the connecting part that is actually being verified, it is appropriate and accurate from the angle that the user wants to see or the angle that the user wants to write. A bar arrangement state can be realized.

It is an example of the three-dimensional image of the floor plan displayed in the reinforcement arrangement verification support device by the present invention. It is an example of the two-dimensional image of the floor plan shown in FIG.

Hereinafter, an example of an embodiment of a bar arrangement verification support device according to the present invention will be described in detail together with a manufacturing method thereof based on the drawings.
The example shown in FIG. 2 includes a recording medium such as a CPU, ROM, RAM, and hard disk, an input / output interface, a communication interface, etc., and an operation system (OS) and an application program (AP: “bar arrangement verification support program”). This is an example realized as a computer system (three-dimensional CAD for buildings) in which a program such as “is included” is installed (see FIG. 2B).

The example of the bar arrangement verification support device shown here is a three-dimensional CAD for buildings having an editing function for editing three-dimensional coordinate system building data (data digitized including members included in the frame). In addition, as a part of the function, bar arrangement verification support means for creating a bar arrangement verification support image from the building data is added.
In this example, after the support image for bar arrangement verification is displayed on the display screen by the function of the bar arrangement verification support means, the three-dimensional image is displayed with the editing function of the three-dimensional CAD for building. Change and modify and save the building data with modified bar arrangement.

  The three-dimensional CAD for building in this example has a mouse object (designating means) 1 for inputting a user's instruction, and the editing function for editing various data based on the instruction input by the mouse object 1. Created object 3, cutout object 4 for creating a support image for bar arrangement verification based on instructions input with the mouse object 1, building data created with the created object 3 or the cutout object 4, and other buildings It has the structure provided with the display object 5 which displays the building data object 2 which manages the data regarding an object, the building data created by the said creation object 3 or the said cut object 4, and the data regarding other buildings (FIG. 2 ( A)).

  The mouse object 1 moves the pointer of the display screen in accordance with the mouse operation, and the contents (commands) and the screen coordinates (coordinates of the screen coordinate system) generated by the mouse operation are displayed on the created object 3 or the cutout. Send to object 4.

The display object 5 has a configuration including a graphic object and a display matrix (affine transformation matrix).
The display object 5 is the building data created by the created object 3 or the cut object 4 or the like by various commands given to the display object 5 such as a command output by the mouse object 1 or Data representing the form and structure of the building, which is a component of the building, in coordinates (hereinafter referred to as “frame data”) and its projection line data are graphic objects (such as DirectX (registered trademark) or OpenGL (registered trademark)) To display on the display screen.

The building data object 2 is obtained by dividing the building data created by the created object 3 and the cutout object 4 into housings constituting the building, etc. In the form of each recording means.
The building data object 2 individually stores the frame data created by the created object 3 and the frame data (verification data) created by the cut object 4.

The creation object 3 creates the frame data by the editing means, or combines them to edit the building data such as a floor plan, a ceiling plan, an elevation, and a plan view.
The building data or the frame data created by the created object 3 is, for example,
The data is stored in the building data object 2 as data in a predetermined format such as DXF format.

For example, the building data and the frame data of the floor plan (see FIG. 20) are the attribute data of the frame included in the floor plan, the bar arrangement list data of the reinforcing bars arranged in each frame, and the frame. It consists of data on the reinforcing bars used (hereinafter referred to as “rebar data”).
Note that the attribute data specifies, for example, the hierarchy constituting the building, the enclosure classification such as pillars or beams included in the hierarchy, and the enclosure axis and enclosure skin (the surface is assumed to be a thin skin) of the enclosure. It is data to be.

  For example, the building data object 2 has a character string such as “1F” in the hierarchy, and a character string such as “post” in the case classification, for example. On the axis, the points P0, P1, P2,. . , Pn and the like, and in the cross section of the housing, the cross sections D0, D1, D2,. . , Dn, etc., points P0, P1, P2,. . , Pn as polygons constituting a plane passing through, and in the case skin, triangles S0, S1, S2,... Divided into quadrilaterals including the sides of the cross sections Dn and Dn + 1. . , Sn and their skin coordinates (see FIG. 3).

As the skin coordinates, the plane or curved surface of the body skin is stored as, for example, a linear function in the U1, V1 directions, a subdivided mesh, or coordinate data of each triangle constituting a triangle group (see FIG. 4).
The linear function gives a virtual grid line to a plane or curved surface, and, for example, a method of changing the amount of increase in the normal direction in proportion to the distance from the starting point of the grid line for each line. Are defined by mathematical formulas or programs.
For example, in the example shown in FIG. 4, a point where the parameter Vt is set in increments of 0.2 is provided on the Bezier curve of VP0 to VP3 in the V1 direction, and the Bezier curve UP0 to UP3 in the U1 direction is translated. Furthermore, the mesh surface is obtained by translating the parameter Ut of the Bezier curve in the V1 direction in increments of 0.2.
If this is further divided into triangles within an allowable error range, FIG. 3D is obtained.

  The bar arrangement list data is data including use information and arrangement information of reinforcing bars included in each case for each case constituting the building.

The reinforcing bar data is data such as a reinforcing bar name (attribute), a reinforcing bar material, a reinforcing bar axis, a reinforcing bar diameter, and the like of the reinforcing bars included in each case. It should be noted that the skin coordinates and the like of the reinforcing bars are appropriately generated by a process of creating a pseudo polygon from the reinforcing bar diameter and sweeping along the rebar axis line (rebar alignment). By selecting such a method, it is possible to prevent the recording area of the recording means from being consumed unnecessarily.
The rebar axis is a point, a straight line, or a curve represented in the editing space of the three-dimensional coordinate system in the three-dimensional CAD for buildings.
The curve is a circle, an arc, an ellipse, an elliptic arc, a parabola, a hyperbola, a Bezier curve, a clothoid curve or another curve, which is a line segment defined by a mathematical expression or a function.

The rebar axis name and the rebar diameter (see FIG. 3E) are, for example, T0-diameter 0, T1-diameter 1, T2-diameter 2,. . . Hold as Tn-diameter n.
The rebar diameter is the diameter of the rebar. The radius of the reinforcing bar is the distance from the reinforcing bar axis to the skin in the direction perpendicular to the reinforcing bar axis.

  The cutout object 4 is a two-dimensional image (see FIGS. 18 to 20 and 23) or a three-dimensional image (see FIGS. 21 and 22) composed of the building data or the frame data of the floor plan of the designated floor. Display processing (see Fig. 5), specified detection processing to specify the connection part of the column beam to be subjected to bar arrangement verification from the floor plan displayed on the display screen, etc. Body detection processing to detect the pillars and beams that make up the part, connecting portion cutting processing to cut out the specified connecting portion with the specified location as a boundary, basic support image creation processing to create a basic support image of the cut out connecting portion, Beam cross-section image creation processing to create an external appearance image (including the cross section of the beam) of the cut out connection part, edit the support image for bar arrangement verification that combines external images seen from multiple directions Support picture Edit processing, line-of-sight change processing for changing the display angle of the connecting portion cut out from the building data, and mark processing for displaying the cut out connecting portion with highlights on the floor plan (with a created mark) are sequentially performed ( FIG. 20).

[Display processing]
In the display process, the control unit of the cutout object 4 receives the designation of the hierarchy to be displayed based on the command from the mouse object 1, and the building data object 2 receives the designation of the building data object 2. A command for searching column data (column frame data) and beam data (beam frame data) included in the specified hierarchy is output from all the building data or the frame data stored in the recording means.

The building data object 2 that has received the command outputs a search result to the cut object 4.
The cut-out object 4 that has received the search result creates the projection line data based on the building data or the frame data of the floor plan and outputs it to the display object 5, for example. The display object 5 is a graphic module and a display matrix that it holds, and displays the projection line data received from the cut object 4 on the display screen as a surface or line of the body skin (FIGS. 5, 20, and FIG. 23).

[Specified detection processing]
In the designation detection process, the control unit of the cutout object 4 receives a designation of a casing to be considered for reinforcement arrangement based on a command from the mouse object 1, and the designation detection unit of the cutout object 4 receives the designation. On the other hand, a command for specifying the specified chassis is output.
The designation detection means for the cut object 4 that has received the command specifies, for example, the frame designated by the point operation (for example, “click operation” by the mouse) on the floor plan displayed on the display screen.
At that time, the designation detecting means guides the screen normal at the screen coordinate point designated by the click operation, converts the screen normal to XYZ coordinates of the editing space, and the screen normal in the editing space. Detect intersecting enclosures.

  If the detected body is a pillar, the designation detection means notifies the control unit of the cut object 4 of the pillar and proceeds to the next process. If the specified body is not a pillar, the cut object 4 This is notified to the control unit, and the user is warned through the display object 5 and the like, and waits until the column is designated by the user's input operation (see FIG. 6).

[Case detection process]
In the case detection process, the control unit of the cut-out object 4 receives designation detection of a case (column) serving as a detection target from the designation detection unit, and is designated for the building data object 2. Outputs a command to specify the chassis connected to the chassis.

The building data object 2 that has received the command searches the column data and the beam data of the specified hierarchy from all the frame data stored in the recording means of the building data object 2, and the specified detection The skin coordinates of the column detected by the means and the skin coordinates of all the beams included in the floor plan displayed on the display screen are compared by solid Boolean calculation, etc., and it is recognized that they are connected to the specified column. The beam data of the beam recognized to be connected to the designated column is stored in the recording means of the cut object 4 (see FIG. 7).
As described above, in this example, each of the function means and the function objects for performing the designation detection process and the chassis detection process constitute a linked chassis specifying means.

[Cut-out processing]
The connecting part cutting processing is performed by using a part of the building (1 block) having an optimal cross section for verification of reinforcement arrangement as the verification data of the connecting part from the enormous building data including the frame data. This is a cutting process (see FIG. 21).

The “part of the building having an optimal cross section” is the connecting portion having a designated column as a base, and the “optimal cross section” is perpendicular to the frame axis of the frame to be cut. And a cross-section that satisfies that it is cut at a position that is not too short and not too long with respect to the base point of the casing that is the base of the connecting portion.
Here, “not too short” means the length of the case body to be cut at that time, the length of the reinforcing bars contained in the case and the length of the reinforcing bars, etc., and “not too long” means It is a length that does not waste the paper used for verification of the streak state or the display area of the display device.

(Cut out the beam)
In the connecting portion cutting process in this example, the connecting portion cutting means of the cut object 4 receives the output of the connecting case specifying means, and is connected to all the pillars detected in the case detecting process. For a beam, a cutting point on the beam axis that is separated from the contact surface (the base point) of the column by an arbitrary distance L, and a plane that passes through the cutting point and points in the beam axis direction of the beam is a normal line Is created (see FIG. 8).

The arbitrary distance L is determined based on a distance desired by the user. When the cutting point exists inside another object (for example, “pillar”), the arbitrary distance L is a distance L to a point reaching the outside.
Specifically, the arbitrary length L is a length of about 0.3 to 3 times the width of the case to be cut in accordance with the crossing angle of the case at the connecting portion (for example, the case width is inclined with respect to the orthogonal direction). (Based on the length divided by the cosine of the corner).

  The connecting portion cutting means is included in a surface existing on the column side in the normal direction of each cut surface while cutting the beam skins and beam axes of all the beams detected by the frame detection processing at the cut surface. The frame data (column frame data) of the beam skin and beam axis is stored in the recording means of the cut object 4 (see FIG. 8).

(Cut out the pillar)
In the connecting portion cutting process, the connecting portion cutting means further connects the connecting surfaces of all the beams connected to the column from the start point of the column axis of the specified column (either the upper end or the lower end of the column). Save the vectors up to the top and bottom of.
The connecting section cutting means obtains the cutting point on the column axis from the shortest vector and the longest vector for each beam, and creates a cutting plane passing through the cutting point and pointing to the column axis direction of the column. In addition, the column skin and the column axis of the column are cut by the cut surface of the column, and the frame data (beam frame data) existing on the beam side in the normal direction of the cut surface is recorded on the cut object 4 Save to.

  At that time, the connecting portion cutting means detects the connection surface between each beam and the designated column, and first designates the area occupied when the connection surface is translated along the beam axis of the beam. A region in the column axis direction shared by the column axis of the column (hereinafter referred to as “shared region”) is guided with respect to all detected connection surfaces of the beams, and is stored in the recording unit of the cut object 4 .

Next, the connecting portion cutting means of the cut object 4 sets a “range axis” between the highest end point and the lowest end point of all the shared areas, passes through both end points of the range axis, and A frame (column) cut along a plane perpendicular to the column axis is detected (see FIGS. 9, 10, and 21).
Similarly to the beam cutting process, a cutting point on the column axis that is separated from the contact surface (the base point) of the beam by an arbitrary distance L is obtained, and a vector that passes through the cutting point and points in the beam axis direction of the column is obtained. You may create the cut surface used as a normal line.

(Rebar cutting)
Further, the connecting portion cutting means combines the column frame data derived by the above connecting portion cutting processing (beams / columns) and the skin coordinate group of the body skin constituting the beam frame data by solid Boolean operation (OR operation). Then, a skin coordinate group (verification frame) of the connecting portion in which the designated column and all the beams connected to the column are combined is created and stored as verification frame data in the recording unit of the cut object 4.

Next, a portion overlapping with the verification frame data is extracted (removed) from the reinforcing bar data of the building data (or the frame data) including the connecting portion as a reinforcing bar alignment included in the range of the verification frame, and the reinforcing bar alignment is extracted. A process of storing the data in the recording means of the cut object 4 is performed (solid and line AND operation).
In this example, a connecting part cutout that cuts out the connecting part composed of the casings detected by the specifying means and the connecting casing specifying means as the verification data consisting of the verification frame data and the reinforcing bar linear data as described above. The processing of the means is terminated.

[Support image creation process]
(Basic support image creation process)
In the basic support image creation process, the support image creation means of the cut object 4 creates, for example, an XY projection plane whose normal is the Z-axis (building coordinate system) direction of the frame, and the XY projection plane The projection lines are generated based on the skin coordinates of the rods and the skin coordinates of the reinforcing bars created from the reinforcing bar alignments included in the verification data stored in the recording means of the cut object 4, and the projection lines are A basic support image is created by projecting onto the XY projection plane.
When the skin of the frame or the reinforcing bar is a curved surface, projection line data including the outline of the triangle group can be generated by the above method by subdividing the curved surface in advance by a triangle group.

Here, the skin coordinates of the casing and the reinforcing bar projected onto the XY projection plane are the coordinates of the surface or the edge line.
The edge line is an outline of an adjacent surface where the normal intersects at a specified angle or more, or an outline of a surface which is considered as a single surface by collecting adjacent surfaces where the normal intersects at less than the specified angle. Indicates the outline of the surface (surface facing outward) having a vector component opposite to the operator's line of sight (hereinafter referred to as “line of sight”).

  At that time, the support image creation means performs hidden line processing on the obtained frame data of the connecting portion to create the projection line (see FIGS. 11 and 12).

Here, the hidden line processing means displaying a part (line or surface) that should be hidden behind an opaque object in front when it is displayed on the screen as a line drawing with computer 3D software. It is a process to avoid.
At that time, the hidden line processing means extracts a triangle (a triangle facing outward from the screen) having a normal having a vector component opposite to the line of sight from a triangle formed by subdividing the cuticle of the cut body and the reinforcing bar skin. Then, a triangular prism is created by extending the extracted triangle group in the direction opposite to the normal vector.
Subsequently, a Boolean operation is performed on the surface of each triangle with the triangular prism, the shared portion is deleted, and the polygonal skin that is removed from the shared portion is divided again into a triangle group.

  Finally, the angle of intersection of the adjacent triangles among the remaining triangles is derived and inspected, and the outline of the adjacent triangle where the normal of each of the adjacent triangles intersects less than the specified angle (single curved surface configuration) By deleting the contour line of the surface that can be regarded as a surface and not originally subdivided unless it is subdivided for convenience of processing, and by setting the Z-axis component that is the height (depth in the extension direction) of each triangular prism to zero Then, a projection line to be projected onto the XY projection plane is created (see FIGS. 12 and 13).

When the above-described hidden line processing is performed on the cadaver epidermis and the reinforcing bar epidermis that are in an overlapping positional relationship, all the reinforcing bar epidermis existing in the cadaver are erased by the cadaver epidermis.
In order to avoid such a situation, in the hidden line processing, first, the triangle having the normal with the vector component in the direction opposite to the line of sight (triangle facing outward) is deleted, and the body epidermis outside the screen is removed. At the same time, the normals of the triangles (triangles facing inward of the screen) constituting the remaining body skin (the body skin inside the screen) are reversed. As a result, only the body skin existing behind the reinforcing bar skin is extracted with respect to the projection surface, and after the hidden line processing, only the reinforcing bar wire and the outer contour line of the housing are extracted as projection lines projected onto the XY projection surface. The
Note that the reverse of the normal is specifically to replace the clockwise triangle coordinates counterclockwise (clockwise and counterclockwise are opposite depending on whether the coordinate axis is a right-handed coordinate system or a left-handed coordinate system. become).

(Beam section image creation processing)
In the beam cross-sectional image creation processing, the support image creation means of the cut-out object 4 does not indicate the beam axis direction of the cut point of the detected beam axis of each beam, not the Z-axis (building coordinate system) direction of the frame. A projection plane (frame projection plane) that is a normal line is created, and the verification data stored in the recording unit of the clipped object 4 is applied to the frame projection plane in the same manner as the basic support image creation process. A projection line is created based on the skin coordinates of the included rod and the reinforcing bar skin coordinates created from the rebar alignment, and the projection line is projected onto the frame projection plane to create a beam cross-sectional image.

At that time, for example, the support image creation means detects the beam axis direction V of each cutting point for all detected beams, and uses the cutting plane of the beam as a base point and a vertical direction V0 perpendicular to the beam axis direction. Lead.
Next, a rotation matrix having the V0 and V as the Y axis and the Z axis is derived, and the verification data is rotated (see FIG. 14). Finally, hidden line processing similar to the basic support image creation processing is performed on the cut body (see FIG. 11), and a projection line projected onto the XY projection plane is created (see FIGS. 12 and 13).

(Support image editing process)
In the support image editing process, the support image editing unit edits the basic support image or the beam cross-sectional image created by the cut object 4 as a support image for reinforcing bar arrangement, and serves as attached data of the verification data. It is stored in the recording means of the cut object 4 or outputted to the building data object 2.

For example, the basic support image including the rebar cross section and the beam cross-sectional image are calculated so that an XY rectangular occupation area is calculated from each projection line data projected on the XY plane or from each projection line data and does not overlap each other. The arranged images are edited and stored in the recording means of the cutout object 4 as auxiliary data of the verification data, or output to the building data object 2.
In this way, by arranging and displaying appearance images including cut surfaces of the connecting portions constituting the building as viewed from the directions of the various shafts, the reinforcing bars contained in the plurality of housings in the connecting portions are displayed on the respective shafts. Since the verification can be performed from the front of the direction, the efficiency of the correction work is also increased.

As described above, when editing the image in which the basic support image and the beam cross-sectional image are arranged, the beam cross-sectional image is moved while the basic support image viewed from the Z-axis direction of the frame coordinate system is fixed.
At this time, the support image creation means guides the XY rectangular area of the basic support image to “Box_A” and guides the rectangular area of the created beam cross-sectional image to “Box_B”.
Next, the midpoint of the right side of the “Box_A” is A, the midpoint of the left side of the “Box_B” is B, a vector for moving the point B to the point A is derived, and the projection line data of the beam is The “Box_B” is moved by the amount of the vector so that the beam cross-sectional image is moved in the same way by the amount of the vector.
Then, “Box_B” is copied to “Box_A” to form a new “Box_A”, and the above process is repeated for all beam cross-sectional images.
Finally, the projection line data of the frame data included in the XY rectangular area of the basic cross section and the rectangular areas of all the beam cross sections (attached data of the verification data) is stored in the recording unit of the cut object 4; Or it outputs to the said building data object 2 (refer FIG.15 and FIG.16).

(Gaze change processing)
In the line-of-sight change process of this example, the mouse object 1 derives the direction and amount of the drag operation and the drag start point coordinates from the contents of the mouse operation on the editing screen.
On the other hand, the line-of-sight change means receives the drag start point coordinates, and guides the screen normal passing through the drag start point coordinates, as well as the designation detection means, and the screen normal and the frame in the editing space. Guide the intersection.

Subsequently, the line-of-sight changing means receives the direction and amount of the drag operation from the mouse object 1 and changes the line of sight displaying the connecting portion cut out by the connecting portion cutting process according to the direction and amount. .
That is, the line-of-sight changing means determines the rotation direction of the connection part cut out by the connection part cutting process and the rotation amount in the rotation direction around the intersection (reference point), and The display matrix for performing the determined rotation is created, the line of sight of the image displayed on the display screen is changed through the affine transformation (see Patent Document 7) with respect to the skin coordinates of the connecting portion, and as a result, the display screen The displayed image is appropriately changed to the two-dimensional image (depth component = 0) or the three-dimensional image.

Further, upon receiving the direction and amount of the drag operation from the mouse object 1, affine transformation is performed to change the scale or movement amount for displaying the connecting portion cut out by the connecting portion cutting process according to the direction and amount. The two-dimensional image or the three-dimensional image having a desired size and inclination may be obtained freely by performing enlargement / reduction and parallel movement of the image displaying the connecting portion.
Note that the line-of-sight changing means of this example displays an image whose line of sight has been changed using the display object 5 on the display screen.
The line-of-sight change process may take a method of changing the line of sight upon receiving a definite input from the user through an input dialog in addition to the information from the mouse object 1.
