This is an 3-D network play tank battle game for UNIX/X with Mesa or OpenGL. It is similar to the old "Battle Zone" arcade game and the game "Spectre" for the Mac. You drive a tank through a 3-D rendered world, dodging and fighting all the other tanks. You can have either robotic opponents (computer controlled), human opponents across a network, or a combination of the two. A variety of features (fog/night vision conditions, heads up display, etc.) make game play varied and more interesting. This program was written as a final project for a computer graphics course, and was originally developed under Linux. WWW: http://step.polymtl.ca/~coyote/graphics_tank.html
