Application of 3D Reality Technology Combined with CAD in Animation Modeling Design

Computer three-dimensional animation is a new type of animation with the development of computer software and hardware technology in recent years. Three-dimensional animation should apply the software of three-dimensional animation technology to establish a virtual world in the computer. In this virtual three-dimensional world, designers build animated character models and scene models according to the shape and scale of the objects to be represented. Then set the motion trajectory of the character model, the motion of the virtual camera and other animation parameters according to the requirements, and then assign specific materials to the model and add lights to the model. Then the computer can automatically calculate and generate the final continuous picture. Under this background, the research on 3D animation character shaping in this paper is to analyze and study the market situation from the standpoint of small-scale 3D animation companies (teams) with relatively weak technology, and through the author's own creative practice, this paper summarizes some principles for the design and production of 3D animation characters, and tries to improve the education system of 3D animation character design. It promotes the production and dissemination of 3D animation and distinct 3D animation characters. Starting with the comparative research method, this paper summarizes the differences of 3D animation character shaping from the comparison of the characteristics of 3D animation and traditional animation, and then summarizes the efficient ways and methods of how to shape 3D animation characters by combining practice with theory.
