Hey all, I'm currently looking to write my own 2D software triangle rasterizer and am having difficulties in finding good resources to do so. I currently can draw the triangle, but not fill it in (the tough part). I need to find a decent resource that explains how to properly do edge walking and interpolation down the edges of a triangle, as well as scan-convert across. Thanks!

this is not exactly what you're looking for, but a pretty good alternative if you can get your head around it.

This gives you a nice insight of a triangle rasterizer:

As a start I would recomend this one:

Click search then Google. Enter triangle rasterization in the field. Good luck. It's been discussed so many times here. I also already gave most of what has to be known about it.
