Graphics research framework This is pretty much just a laundry-list of features with some pretty pictures. Useful stuff - Flexible scene-graph with multiple render targets
- Virtual File System for seamless loading from regular directories, Quake PAK archives, or ZIP files.
- Limited GUI support (transparent text windows which can be dragged around or typed into, great for debugging)
Level formats supported - Quake level loading (.BSP, version 0x1D)
- Quake II level loading (.BSP, version 0x26)
- Quake III level loading (.BSP, version 0x2E)
Model formats supported - Quake II model loading (.MD2)
- Quake III model loading (.MD3)
- Molecule loader (.M3D)
- 3DS loading (.3DS, incomplete)
Textures/materials supported - JPG
- PNG
- TGA
- PCX
- BMP
- Q2 .WAL
- Q3 .shader
 
Demo effects: - Tunnel
- Infinite 3D grid
- Tie-dye (composite effect)
- Sinus Scanlines
- Copperbars
- Iterated function systems
- Multiple morph modes
- Pre-defined matricies for the morphers: Binary, Coral, Crystal, Dragon, Fern, Floor, Spiral, Swirl, Tree, Triangle, and Zig-zag
- Particle systems: Snow, rain, grid-bugs, explosion debris
Full-screen processing: - Radial blur
- Roto blur
- Motion blur
- Glow blur
Procedural surfaces: - Sphere
- Ellipsoid
- Cylinder
- Rectangular prism
- Torus
- Superellipsoid
- Supertoroid
- Elliptic Torus
- PQ torus knots
- Springs
- Bezier curves
- Supershapes
- Spherical harmonics
Misc. features: - Texture-mapped fonts
For a neat effect, text strings can be bound to any of the path objects, such as the PQ torus knot. - Skydome (including real sun position and CIE clear/cloudy sky luminace)
- FBm generated heightmaps
- Heightmap from image
- Skybox
Generated surfaces (no parameters): - Pisot Triaxial
- Triaxial Tritorus
- Pillow Shape
- Whitney Umbrella
These are all generated using a general purpose parameterized-surface generator with different parameter matricies.
