Three-dimensional animation system of computer and animation method

Abstract

The invention discloses a three-dimensional animation system of a computer. The three-dimensional animation system is implemented by few data and is efficient and diversified, and redundancy of the data can be reduced. The three-dimensional animation system is characterized in that an animation control module 1 specifies shape data, specifies hierarchical data, specifies attribute groups and specifies state information; and an animation algorithm module 3 acquires the shape data from a shape data processing module 5, acquires the hierarchical data from a hierarchical processing module 4, acquires attributes from an attribute group processing module 2 and acquires action data recorded in the state information from an action data processing module 6. The action data which are acquired corresponding to numbers of the attribute groups are changed into the shape data according to the hierarchical data; and then a three-dimensional graph drawing module 7 carries out three-dimensional drawing processing for the changed shape data to generate images, and graph rendering is carried out in a rendering module 9, and the images are displayed in a display module 10.

Description

technical field [0001] The invention relates to a system in the field of three-dimensional computer animation, in particular to a three-dimensional computer animation module of complex objects with layered structures such as characters. Background technique [0002] In the past, when using three-dimensional computer graphics (hereinafter referred to as 3D CG) to generate animated images of animals or people, the main picture method of sequential kinematics and joint angles based on the skeleton method (see, for example, Non-Patent Document 1) was used as a generalized method. main screen method. use below Figure 2 to Figure 4 Briefly explain these methods. [0003] character's actions figure 2 The path direction and movement of the skeleton structure generate the movement of the whole body, and the local movement of the body is generated through the transformation of the local coordinates of the skeleton structure at the joints. The action of the character is achieved b...

Problems solved by technology

[0007] The first question is, since the skeleton structure of the state of holding the object is different from that of the state of not holding it, it is necessary to have shape data in the state of not holding it and shape data in the state of holding it. How many types of objects are there? , how much CG character data is needed

The second problem is that due to the above-mentioned different skeleton structures, even if the body movement data is the same, there must be two kinds of movements in the state of holding the object and the state of not holding the object

In such a state, if the variety of actions including facial expressions as mentioned above is to be realized, the amount of data will increase explosively.
