Research on Physically-based Computer Animation

In order to estimate the physical characteristics of the mechanical system and shorten the development cycle, this paper studies the principles and related technologies of the generation of physically-based animations, and combines the Bullet physics engine to simulate the dynamics of rigid bodies, and produce physically-based animations. The basic principle of physics animation is based on dynamic equations. The numerical solution technology is used to solve the dynamic equations. The actual motion of the rigid body will not penetrate, and collision detection is required. The Bullet physics engine is used to calculate the motion process of a rigid body, and OpenGL is used for rendering, and the two are combined to realize the simulation process.
