DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional animation processing system using an electronic computer, and more particularly to a three-dimensional animation processing system in which an object three-dimensional processing method in animation processing is improved.

[0002]

2. Description of the Related Art In recent years, attention has been paid to animation processing using an electronic computer. In general, this is a process for expressing a movement of an object by rapidly switching and displaying a series of objects having slightly different display positions. When the starting point and the ending point of the object are designated, the frame between them can be automatically generated. As this kind of conventional technology, for example, “Macro Mind Direc” written by Toshihide Ito
The technology described in “tor Japanese Edition [AtoZ]” (BNN, 1991) is known. In this technology, when performing animation processing, the display position of an object called a score on the stage, the display priority, and the like are given by giving the display position of the object to a screen on a computer for playing an animation called a stage. It is automatically defined in the window to be managed, and changes the display position of the object little by little to change the designated frame at a high speed to give the object a motion. Here, in order to express the movement of the object in the perspective direction, the object subjected to image reduction or image enlargement processing or the like in advance is designated as a continuous frame. Further, in order to display a plurality of objects in the same frame, each object is designated as having a different channel number which is an object number in the frame. If the display positions of multiple objects overlap on the stage, the object with the larger channel number is displayed preferentially. If the perspective relationship of the objects is switched, the channels of each object are switched from the subsequent frames. Will be specified.

[0003]

In the above prior art, the size is changed in order to express the movement of the object in the perspective direction, and the channel is changed in order to specify the display priority when a plurality of objects overlap. And there is a problem that usability is poor. The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-described problems in the conventional technology and to specify a method for expressing the movement of an object in a perspective direction in animation processing. An object of the present invention is to provide a three-dimensional animation processing system that simplifies a method of specifying a display priority when objects overlap.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a system for performing animation processing for giving a motion to an object by displaying a continuous object at a high speed using an electronic computer. Means for defining data, means for defining the display position of the object as three-dimensional information in the vertical, horizontal, perspective directions, means for defining the passing point and passing time of the object, and information defined by each means A three-dimensional animation having means for calculating the size of the object on the screen at each time, reducing or enlarging the image, and determining the display priority when a plurality of objects overlap. Achieved by a processing system.

[0005]

In the three-dimensional animation processing system according to the present invention, since the display position of the object is defined as three-dimensional information in the vertical, horizontal, and perspective directions, the size and display priority of the object at each time are determined. Can be automatically performed, and the effect of simplifying the specification method for expressing the movement of the object in the perspective direction in the animation processing and the display priority specification method when a plurality of objects overlap is obtained. It is something that can be done.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an animation processing system according to one embodiment of the present invention. In the figure, 100 is an image data definition unit, 110 is an object information definition unit, 120 is a motion definition unit, 1
Reference numeral 30 denotes a calculation / processing unit, and 140 denotes a display unit. When creating an animation by the animation processing system shown in the present embodiment, the user first defines image data of an object to be used as bitmap data in the image data information 300 using the image data definition unit 100. An example of this is shown in FIG. Subsequently, using the object information definition unit 110, the image data information 3 used in one frame
00 and its display position (X, Y, Z) in object information 3
Defined as 10. One example of this is shown in FIG.

[0007] Finally, using the motion definition section 120, which object information 310 is used at which time is defined in the motion information 320. An example of this is shown in FIG. The calculation / processing unit 130 calculates the size of the object on the screen at each time based on the above-described definition information, performs reduction or enlargement of the image, and sets the display priority when a plurality of objects overlap. decide. The display unit 140 displays the object at each time based on the result processed by the calculation / processing unit 130. Hereinafter, the operation of the calculation / processing unit 130 will be described in detail based on the flowchart shown in FIG. Step 200: When performing the animation process, the calculation / processing unit 130 first extracts the motion information 320 from the motion definition unit 120 one by one.

Step 201: Next, it is determined whether or not object information 310 is defined in the extracted motion information 320. Step 202: As a result of the above determination, the motion information 32
0, if the object information 310 is defined, the image data information 3
00 are taken out one by one. Step 203: coordinates (X, Y, Z 31 in FIG. 4) defined in the object information 310 extracted in step 202
2 to 314), the image of the object is reduced or enlarged according to the perspective direction. FIG. 6 shows the object at times t ₁ and t ₂ on the three-dimensional coordinates. FIG.
As shown in the figure, the coordinates of the object at time t ₁
(X ₁ , Y ₁ , Z ₁ : 600 in FIG. 6) to move to coordinates (X ₂ , Y ₂ , Z ₂ : 610 in FIG. 6) at time t ₂ . _{If 1} = 0, the coordinates (X ₁ , Y
₁ , Z ₁ ), the size of the object remains the size defined in the image data information 300.

In the case of coordinates (X ₂ , Y ₂ , Z ₂ ), since Z ₁ <Z ₂ , the following image reduction is performed to express the movement in the perspective direction. First, when the distance from the viewpoint 620 to the Z ₁ and K, the coordinates _{(X 2, Y 2, Z} 2) object change rate (Size) is determined by the following equation.

(Equation 1) The image at the coordinates (X ₂ , Y ₂ , Z ₂ ) is reduced according to the above equation (1). FIG. 7 is a two-dimensional diagram showing the objects at times t ₁ and t ₂ . The reduced image data is displayed on the screen as shown in FIG. Step 204: When the image reduction or enlargement processing of all the image data information 300 in the object information 310 is completed, the display priority according to the perspective direction is determined.

FIG. 8 is a three-dimensional view, and FIG. 9 is a two-dimensional view at time t ₁ ,
It is a diagram showing a difference of the display priority of the object in t _2. FIG. 8 shows coordinates in the animation processing of FIG.
(X ₃ , Y ₃ , Z ₃ ). Perspective Direction Z is Z ₁ <Z ₃ <Z ₂ becomes, on the screen, is displayed as shown in FIG. 9. As described above, according to the present embodiment, since the display position of the object is defined as three-dimensional information, it is possible to automatically change the size of the object and the display priority in the perspective direction. It should be noted that the above embodiment is an example of the present invention, and it is needless to say that the present invention is not limited to this.
