Research On Human Body Animation

The computer aid animation is a high and new technique; it is the thing that combines the art and the computer graphics together. Accompanying with the high speed devolvement of computer hardware and graphic arithmetic , it synthesize the computer science, art, mathematics, physics with the knowledge of the other and related course, the computer aid animation make abundance sequence virtual real images on the screen.In computer graphics, human body animation is one of the challenging courses. It have a extensive and applied future, and plays an important role in the films, computer game, , the animation design of advertisements, virtual reality etc. The human body imitates make it possibility and can really make mankind to know the details in the process in advance. This helps to make the robots that do " impossible mission that completed" of human. And the human body sport also is very complex course, there are a lot of things need to be done.This paper analyses human body animation technique; bring up the method of human body animation based on geometry. Based on OpenGL and using the developmental tool Visual C++, this paper makes the right human arm model. This model includes the right upper arm imitated by cylinder; elbow to be imitated by surface of sphere and right small arm imitated by cylinder. Then deduced the calculation formula of the important factors, which used for control the actions of the right arm. With the model's structure, using the important factors, the paper realizes to control the real-time animation.
