The software renderer uses Bresenham's line slice algorithm as presented by Michael Abrash in his Graphics Programming Black Book Special Edition with the serial numbers filed off (as such, more just so *I* can read the code easily), along with the Chen-Sutherland line clipping algorithm. The other renderers were more or less trivial in comparison.
