Software Texture Mapping
CS551 Final Project

Whoops! I went and broke this one. On purpose. Maybe if you're nice I'll fix it and re-publish it. Otherwise feel free to do so yourself. All you gotta do is take out this catch that makes it quit during init if it can't find a file that I shouldn't have included in the first place. Oh wait, all I posted was the binary. Let me go dig out the code and fix it up for y'all . . .

This demonstrates software texture mapping, all extremely parallel to OpenGL. It's practically a software implementation of OpenGL - at least the subset of functions which I wanted to implement.

    Features:
  • Fixed-point precision math
  • Perspective-corrected coordinate interpolation
  • 1D, 2D, Cube Map and 3D textures
  • Texture wrapping: repeat, clamp, and mirror
  • Texture magnification filtering: nearest and linear

    The real impressive thing to see is how fast this does linear texture filtering. It's practically no slower than it does nearest-neighbor. Of course I'm sure anyone out there with a bit more enthusiasm in hand-optimizing assembly could outperform my own. No texture minimization. No mip-mapping. Sorry folks.

  • Texture coordinate generation: linear, spherical, cylindrical, and of course manual
