Zed 3d - a document explaining the maths you'll need for 3d. Word and postscript formats of the same file. Zed has an attention to detail and a great way to explain all the math. I highly recommend this to anyone starting to make a 3d engine who doesn't know where to start (start with the math, not the polygon fillers, believe me! the fillers are trivial in comparison). See the bibliography for where to go next.
164 byte pcx loader. Only works on 320x200x256 images (because of video mode and failing to check the image's actual size) and doesn't explain the pcx file format (which is more or less trivial)
