Chapter 21 Research on the Method for Simulating 3D Dynamic Process in Two-Dimensional Space and its Application in Developing Audio and Video Electronic Textbook

摘要

If we use computer to simulate simple form of three-dimensional dynamic process that is virtual or very difficult to achieve in reality directly in the two-dimensional space, we will reduce the development difficulty of simulation process. This paper introduces the simulation methods and key technologies by some relevant examples in "Audio and Video Electronic Textbook of Mechanical Drawing." The examples include the formation process of gyration curved surface, the process of an object being cut by a plane, the decomposition process of a combined object. The Rash animation software is mainly used in the simulation process, and AutoCAD software and Photoshop software are the tools used for preparing materials. The results show that simple form of three-dimensional dynamic process can be simulated very realistically in the two-dimensional space, not using the tools of three-dimensional animation.
