Project X was my second 3D engine, which served as a testbed for a number of graphics algorithms and effects. In addition to graphics however, this engine also provided support for physics, game logic, ai, and more.
This engine eventually served as the foundation (almost 2 years later) for my Project Vision 3D Engine, as well as the core for a number of projects at my (undergraduate) university. X was also featured in 2001 on Flipcode's Image of the Day forum.
Thus Project X provided a valuable testing ground through which a large variety of graphics algorithms were invented and implemented.
Project X features the following (partial) list of features:
Static and Dynamic Lightmapping
Custom Map Format
Pre-Computed and Dynamic Radiosity
Simple Physics Engine
Simple Map Builder
Broad Model Format Support
OpenGL 1.4 Support
Multi-texturing with Multi-pass Fallback
Simple Networking Layer
Real-time Debug Engine
