DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below in detail with reference to the drawings. The above-mentioned FIGS. 1 to 4 are diagrams showing configuration examples of a display control table of a display control device of the present invention, and FIGS. 5 to 7 are diagrams showing examples of floating display of objects of the present invention. , Figure 5 shows the case where the object and shadow are enlarged or reduced according to the height (Z) of the object.

shows a case where the object and the shadow are enlarged or reduced according to the height of the object, and the shift display distance between the object and the shadow is changed.

In the present invention, when displaying an object and shading corresponding to the object to display a three-dimensional effect of the object, the display height (Z) of the object is
depending on the size of the object and its shading, and
Means (1) to (4) for changing the positional relationship between the object and its shadow are necessary means to carry out the present invention. Note that the same reference numerals indicate the same objects throughout the figures.

The configuration and operation of the display control device of the present invention will be explained below with reference to FIGS. 1 to 7 while referring to the configuration example of the display control device shown in FIG. As an embodiment of the present invention, a case where the present invention is implemented using a workstation having the hardware configuration as shown in FIG. 8 described above will be described.

As mentioned above, hard disk 1 in FIG.
5, normal display data and shadow display data of the object are stored, and their storage information and display state information are stored in the object/shade data management table (2) in FIG.

[0020] In Fig. 1, X and Y indicate the upper left display coordinates of the object or shadow at that time, the Z data of the object file is the height of the object, and the Z data of the shadow file is the current shadow. This means that the display is performed at the size for the object of the height specified by the Z data.

First, FIG. 5 shows a method for displaying object a according to the object/shading data management table (2) in FIG. 1 and the display size table (2) in FIG. 2. The data for shade a is transferred from the hard disk 15 to display frame memory 12 (20, 60) (see X, Y in Figure 1).
(second display area 2), but since the shadow data is the shadow of an object with a height of 10 (Fig.
(see Z in FIG. 1), convert the size to 100% of the height of 0 in FIG. 1 (see FIG. 2), and place it. The data of object a is similarly placed at the position (10, 50) (see X, Y in Figure 1) (first information display area 1), but the object has a height of 10 (see Z in Figure 1). ), it is converted to a size that is 110% of the size when the height is 0 (see Figure 2) and placed. {See Figure 5(a)} Next, for example, the user changes the display height (Z
) is entered from the keyboard 13 as 50, and a request to change the display height occurs.Then, color data corresponding to the background color is set in the entire area in the display frame memory 12, and the screen is changed. After clearing, the object height (Z
) is "50" and set the size of the shade a to 70.
%, the display data in which the size of object a is reduced and enlarged to 150% does not change the distance between the upper left coordinates of object a in Figure 5 (a) and the lower right coordinates of both (A and B in the same figure). The display frame memory 12 is placed on the display frame memory 12 in this manner. { (See Figure 5(b)} Then, set Z of the display position of object a in the object/shade data management table ■ in Figure 1 to 50, and set X and Y of the display position of shadow a to Figure 5(b). ) Change the coordinates of S1 in the middle and Z to 50.

[0022] The above display size table (■) corresponds to the display height (Z) of object a when determining the display size of the object and the display size of the shade a according to the display height (Z) of the object a. Although this is an example in which the value obtained by dividing the area of the shadow a by the size is expressed as a percentage, it is generally a size of a ratio calculated by a specific function.

Next, an embodiment will be described in which the display distance of the deviation between the object and the shadow is changed. First, a case will be shown in which object a is displayed according to the object/shade data management table (2) in FIG. 1 and the display position table (2) in FIG. 3. In the same way as described above, the data for shade a is transferred from the hard disk 15 to the display frame memory 12.
Similarly, object a is placed at the coordinates (20, 60) of the display frame memory 12 (see X, Y of the shading a in FIG. (see X, Y of a). {See Figure 6(a)} Next, for example, suppose that the user inputs 50 for the display height (Z) of object a from the keyboard, thereby generating a request to change the display height of object a. , sets color data corresponding to the background color in the entire area in the display frame memory 12, clears the display screen, and displays the objects in the object/shade data management table ■ in Figure 1 and the display position table ■ in Figure 3. Referring to the column where the height (Z) of is "50", the data of shading a is shifted from the position where it completely overlaps object a to the lower right by 40% of the object size on the display frame memory 12. Deploy. The data of object a is placed in the same position and size as in the case of FIG. 6(a). {See Figure 6(b)} After that, set Z of the display position of object a in the object/shade data management table ■ in Figure 1 to 50, and set X and Y of the display position of shadow a as shown in Figure 7(b). The coordinates of S2 inside (50=10+40, 90=50+40), Z is 5
Change each to 0.

In the above embodiment, the corresponding shadow a is shifted at the same ratio (%) in the X and Y directions according to the display height of the object, and the display distance is continuously changed. The explanation was given using an example in which the overlapping deviation angle between a and its shadow a is constant, but by setting the deviation display distances in the X and Y directions at different ratios, it is possible to continuously display the overlapping deviation angle while maintaining the deviation display distance. It is clear from the display position table (3) in FIG.

Next, regarding other embodiments, FIGS.
This will be explained using FIG. 7. First, a case will be shown in which object a is displayed according to the object/shade data management table (2) in FIG. 1 and the display size/position table (2) in FIG. 4. In the same way as described above, the data of the shade a is transferred from the hard disk 15 to the display frame memory 12 at the coordinates (
20, 60) (see X, Y of the shade a in Figure 1), but since the shadow data is the shadow of an object with a height of 10 (see Z of the shade a in Figure 1). 110% when the height is 0 in 1 {Display size/position table in Figure 4■
Refer to the column where the height (Z) of the object is “10”}
Convert it to the size and place it.

Similarly, the data of object a also has coordinates (
10, 50) (see X, Y of object a in Figure 1), but the object has a height of 10 (
(see Z of object a in FIG. 1), it is converted to a size that is 110% of the size when the height is 0 (see display size/position table ■ in FIG. 4) and placed. (Figure 7(a)
Reference}Next, for example, if the user inputs the display height (Z) of object a as 50 from the keyboard 13 and a request to change the display height of the object occurs, the display height (Z) in the display frame memory 12 is generated. After setting color data corresponding to the background color in all areas and clearing the display screen, set the object height (Z ) is "50", and display data in which the size of shade a is enlarged to 150% is added by 40% of the size of object a from the position where it completely overlaps object a (display size/position in Figure 4). (Refer to table ■) Place it above the display frame memory 12 shifted to the lower right.

Furthermore, the size of object a is reduced by 150%.
The display data enlarged to object a in FIG. 7(a)
It is placed on the display frame memory 12 corresponding to the upper left coordinates (10, 50) of . {See Figure 7(b)} After that, set Z at the display position of object a in Figure 2 to 50, and set X and Y at the display position of shadow a in Figure 7(b).
Change the coordinates of S3 and Z to 50. Similarly, set the display height (Z) of object a to 70,100
7(c) and (d).

In this embodiment, as is clear from FIGS. 7(a) to 7(d), the display height (Z) of object a
An example is shown in which the display size of object a and shadow a is enlarged by changing the display size of object a and shadow a, and the shift display distance is also changed. In other words, the size of object a is enlarged, the size of its shadow a is reduced, and the shift display distance is changed according to the display height (Z) of object a. Needless to say, this is a good thing.

Furthermore, in the above embodiment, when object a is displayed at a certain display height (Z), the corresponding shadow a is displayed at a position determined corresponding to the display height (Z) of the object. As explained in the example above, when the display position of the object a is moved (by parallel movement, rotation, etc.), the relative position of the object a and its shadow a may be fixed or It goes without saying that the shift display distance, shift angle, etc. may be controlled to be changed depending on the amount of movement.

Furthermore, in the above embodiment, the object a and its shadow a are displayed with reference to the predetermined display size table ■, display position table ■, and display size/position table ■. Although the example has been explained, it goes without saying that a predetermined calculation formula may be used instead of using a table.

[0031] In this way, the present invention provides objects and
When displaying the shading corresponding to the object to give it a three-dimensional effect, the object's display height (Z
) A means for changing the size of the object and its shadow, and the positional relationship between the object and its shadow is provided, and the object and the shadow are changed according to the height at which the object is displayed. The feature is that the size and positional relationship of the objects are changed to express the three-dimensional effect of the object.

[0032]

As described above in detail, the display control method of the present invention expresses the three-dimensional effect of an object by displaying the shadow of the object at the same time as displaying the object. The size of the object and its shadow, as well as the positional relationship between the object and the shadow, are changed according to the display height (Z) of the object to more realistically express a three-dimensional effect. , it is possible to manage the display of objects suitable for a three-dimensional space.
