As the fast development of Computer Graphics hardware and software, the applications of 3D computer animation have been prosperously developed. Involving audience’s life experience, character animation, has the most drama, thus becomes the mainstream of computer animation. Compared to traditional animation, 3D computer animation provides better coloring, spatial effects, and labor saving, therefore, progressively replaces traditional animation, and has the bigger market share in commercial animation. Except different production tools, motion control of character animation between traditional and 3D computer animation basically are the same. Therefore, better 3D computer animation can be achieved, if we can successfully apply the experience in producing traditional animation onto it. This paper studies the basic principles of traditional 2D animation and their application to 3D computer animation. After describing each principles, individual principles are detailed format he motion control point of view, and examined the possibility in reproducing of them in 3D computer animation, using the available animation techniques. Convenient Computer Graphics production tools, with these animation principles, provide the animator an efficient way in producing quality 3D computer animation.
