Commander X16

This demo features 3D rendering to a 256x240@8bpp surface with full transformation calculation, texture mapping and per-pixel depth buffering. The model is a decimated Spot test model  with 512 vertices, 1020 triangles and a 256x64 texture.

So, I wrote this just to get familiar with this system and figure out how to write and optimize a 3D math for it. Also, it would makes a nice reason for me to get up and do some coding streams, as shown here:

Only runs on r39 since I can't find documents for older versions. There's still bunch of incorrect pixels due to depth buffer precision problems.

Controls:

• 
  A/D - Move camera left/right
  


• 
  W/S - Move camera up/down
  


• 
  Q/E - Move camera backward/forward (Z value should be an unsigned number but the UI only displays signed numbers)
  


• 
  J/L - Rotate left/right (yaw)
  


• 
  I/K - Rotate up/down (pitch)
  


• 
  U/O - Tilt left/right (roll)
  

• 
  Add wire-frame rendering stage before full rendering for a preview
  


• 
  Full rendering can be interrupted by a camera change
  


• 
  Add joystick support
