A Computer Method for Perspective Representation of Curves and Surfaces

摘要

This report presents a relatively efficient method for computer generation of perspective plots of groups of objects. The objects are defined in terms of finite space curves and surface patches. A space curve is specified as a sequence of points in space with straight line connections between adjacent points. A surface patch is defined by specifying its coordinates at the mesh points of a curvilinear coordinate system contained within it. (Author)
