for my falcon DSP 3d engine i use SH, and i use DIV ;) it is integer precision, but internally i use 4 bit extra. i have poly filler with and without edgebuffers, and it works well for both.
about speed:
the most important thing is to avoid per triangle clip checks.. it's best to put objects in bounding boxes for that and check clipping per object. this way you also -per object- know what sides to clip. in this case the DIV doesn't slow down too much anymore.. ;)
the source is included with the out demo: http://files.dhs.nu/files_demo/out.zip

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
