CRYTSAL allows a three-dimensional wire frame object to be displayed on the IBM PC's graphics screen by using a rotation and projection to two dimensions. Users may rotate the object about each coordinate axis and change the perspective. CRYSTAL can also produce animation that consists of up to 500 three-dimensional objects, which may be displayed in sequence together with the rotation mentioned above. SYSTEM REQUIREMENTS : This program requires an IBM PC, DOS 2.0+, a Color Graphics Adapter, and 256K RAM. Any optional math chip will be used unless NO87 is defined.
