Summary

Discusses the capabilities of available software and how to use and modify the different programs. Techniques covered include 3D rotations, space curves, Platonic solids, several ways of approximating a sphere, B-spline surface fitting, and hidden-line elimination. Describes how to display perspective views of three-dimensional solids via an interactive program called D3D . Includes the complete source text for all software under discussion. The author uses an IBM PC (or compatible) and the C programming language (or Turbo C), along with a graphics adaptor (such as CGA, EGA, VGA, or HGA), but the techniques are mostly machine-independent.
