In the modern era the 'compute shaders' part of that has become more dominant and lots of fixed function parts of the graphics pipeline have moved to software.
I'd love to see a more modern take on this if someone has run across it.
- pcwalton 2y agoWell, RIVA 128 didn't even have multitexturing, so not much of that is going to be applicable. I don't think that Voodoo era chips even used Pineda rasterization as that article details; they did fancy scanline rasterization.
- kevingadd 2y agoI interpreted rayiner's question as present tense, "what do GPUs look like now" - you're definitely right that most of the architectures I know of from back then were doing scans or (a bit later) tiling.
