Motion simulation method of animation character under granular medium environment

Abstract

The invention provides a motion simulation method of an animation character under the granular medium environment, and relates to computer graphics. According to the motion simulation method of the animation character under the granular medium environment, the motion of natural vision, stable physics and controllable user of the animation character under the granular medium environment can be realized, the making efficiency of motion simulation of the animation character under the granular medium environment in the field of movies, animation and games can be greatly enhanced after industrialization, the algorithm is clear and the process is clear. An animation character motion simulation model based on nerve-muscle-bone is established; an animation character-granular medium interactive anddynamical model is established; and parameter optimization of an animation character control model based on the neural network model is completed and a large-scale motion control unit is introduced,the motion mechanism of real living things is further simulated and the stability of motion and the fault tolerance of the controller can be enhanced.

Description

technical field [0001] The invention relates to computer graphics, in particular to a method for motion simulation of animation characters in a granular medium environment. Background technique [0002] Animated characters are widely used in movies, games, virtual reality and other fields. In recent years, with the further development of related technologies, people have put forward higher requirements for the visual realism of animated characters. As one of the important attributes of the character, the motion of the animated character will directly affect the user's realistic experience. The motion generation methods of animated characters are mainly divided into two categories: data-driven and physics simulation. [0003] The data-driven method collects the motion data of real creatures (human or animal, etc.), and generates the motion of animated characters based on the obtained data. In the past 10 years, motion capture (Motion Capture) technology has been gradually ...

AI Technical Summary

Problems solved by technology

The deformable and easy-sliding properties of granular media will lead to discontinuous generation and non-uniform distribution of local interaction forces, which poses a challenge to the stable and natural movement of animated characters

[0006] The data-driven method needs to build an additional collection experiment environment, and can only cover a limited type of granular media, and cannot directly migrate to the surface of granular media with different properties
