Design system and method for human dynamic bone

Abstract

The invention discloses a design system for a human dynamic bone, comprising an initialization module, a node generation module, a bone constraint module and a collision constraint module, wherein the initialization module is used for initializing model data; the node generation module is used for generating and storing bone node data; the bone constraint module is used for performing regular constraint on a node in the change process; and the collision constraint module is used for performing regular constraint on a bone model in collision. The invention further discloses a design method for a human dynamic bone, comprising the steps of: initializing model data; generating and storing bone node data; performing regular constraint on a node in the change process; and performing regular constraint on a bone model in collision. The system and the method have the advantages of greatly shortening the time required for adjusting lattice vertex parameters by adopting a bone animation or a fabric system in the old scheme, physically simulating the motion and relevant constraints of fabrics and hair more truly and vividly, and efficiently processing the collision inside a fabric and between the fabric and other object.

Description

technical field [0001] The invention relates to a system and method for designing dynamic skeletons of characters, belonging to the field of computer game development. Background technique [0002] Moderate to severe game characters in 3D games often need cloth and hair simulation to better express the characters, and the detailed performance of movements can make the characters lifelike and more attractive to players. [0003] Generally, when dealing with character animation, the game directly adopts the technology of skeletal animation or the technology of physical simulation of cloth system. The basic flow chart of the technology using skeletal animation is as follows: figure 1 ,pass figure 1 From the flowchart, it can be seen that there are defects in the skeletal animation scheme as shown in (1) and (2), including: [0004] (1) Every new set of characters has to go through the process of adding bone skinning and making bone animation. The time-consuming process is pr...

AI Technical Summary

Problems solved by technology

[0004] (1) Each new set of characters has to go through the process of adding bone skinning and making bone animation. The time-consuming process is proportional to the number of bones. The higher-definition model has more bones, and the production time is very large.

Basically, 300 bones plus the time for adjustment and testing will take about three days for an experienced animator;

[0005] (2) The clothes and hair on the characters need to be adjusted by the animator according to the real character's movements. If there is no real person for reference, he will also refer to other game character movements and related videos. Different clothes will have different performances due to different materials. The difference is that it takes a lot of time to call out the clothes and hair of different characters

[0007] (1) The low model is about 3,000 faces, and the high model is about 10,000 faces. The cloth system simulation belongs to vertex animation. It is necessary to adjust all the vertex-related parameters in the grid to perform physical simulation. The clothes and hair of each model need to be adjusted. After the adjustment, run the test and then adjust it repeatedly until it is suitable. This is also very time-consuming;

[0008] (2) The simulation adjustment of the cloth system is to limit the range of distance that the vertex can move. If the distance is adjusted long enough, it is difficult to avoid the problem of cloth interspersed with collision. If the distance is adjusted short enough, it cannot be realistic, and only a small range fluttering

[0009] (3) The movement of each vertex simulated by the cloth system will occupy relatively high system resources due to the relatively large number of vertices
