Java 3D Graphics Engine and Animator

A 3D graphics engine built from scratch in Java. It generates and displays spheres, boxes, and toruses with z-buffering and backface-culling. Supports translations, rotations, and scaling, with flat and gouraud shading. Able to read scripts written in Jon-Alf Dyrland-Weaver's custom motion description language (MDL) to generate animated gifs.

FEATURES

• Scanline
• Z-Buffering
• Flat Shading
• Gouraud Shading

Usage

Compile and run a script

 make
 java mdl <mdl filename>

The animation frames will be placed into animations// from there, you can generate a gif:

 animate -delay 3 ./* (suggested delay)

Provided Scripts

• flatAnim - Flat shading test
• gouraudAnim - Gouraud shading test
• gouraudtorus - Torus test
• discoAnim - Flat shading test with random colors for each polygon
• animtest - general test
• hypnotic
• test

BUGS

Gouraud: shading works for black and white, with black spot at the sphere's rear end. shading is not uniform for colored objects; transitions in layers.
