A Two-View Approach to Creating Computer Animation

: In this paper, we report about the design and implementation of a new interactive animation system. The system is based on the idea that all objects occurring in animation sequences should have two views:the structural view and the shape view. Using our system, the animator can create the two views simultaneously without programming and can manipulate objects by sending messages. Thus, the system is based on an interactive, object-oriented data model implemented on the Macintosh. 1 Introduction The process of generating computer animation can be divided into three phases: object definition, motion specification and rendering. The purpose of object definition is to describe the appearance of an object and its relation to other objects. Motion specification describes how the object moves and changes during animation display. Rendering computes a 2D image of the scene for each frame in the animation sequence from the viewpoint of the camera. To define geometric objects, current animat..
