Interactive 3D Computer Graphics

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.
