Design And Implementation Of 3D Character Animation Editor Based On OpenGL

Research on character animation is one of the most active fields of computer science in the last decade, which involved in many subjects such as interactive graphics, realistic image, kinematics & dynamic and anatomy, and can be applied on teaching, emulation, and digital entertainment and so on. It is the target of this paper to design and realize an editor of character animation. Firstly, this paper introduces model representation and interactive technique in our editor and designs a framework supporting polygon mesh model and a men-machine interactive system with manipulations and commands at the core; and introduces application and optimization of OpenGL poly-view in OS environment. Based on these discussions, the locating and pickup techniques are analyzed detailedly, a new 3D locating arithmetic is presented, and the pickup technique of visible-surface is discussed. Then the paper introduced dendriform model and the principles of animation in skeletal animation, and introduced two improved skeletal animation techniques: vertex blending and bone blending. At last, implement of the whole system is finished. Validation and test proved that the designs presented above are validate, and the interactive system and animation system are up to the standard of real-time.
