THE COMPUTER REPRESENTATION OF SIMPLY DESCRIBED SCENES

Abstract : The paper describes the computer representation of scenes consisting of a number of simple three-dimensional objects. One method of representing such scenes is a space oriented representation where information about a region of space is accessed by its coordinates. Another approach is to access the information by object, where, by giving the object name, its description and position are returned. As the description of an object is lengthy, it is desirable to group similar objects. Groups of similar objects can be represented in terms of a common part and a number of individual parts. If it is necessary to simulate moving an object then only the individual information need be saved. (Author)
