Software Rasterizer On HoldI pretty much have hit a limit with optimization on the rasterizer. I made quite a few improvements with respect to memory access, redundant function calls, and overall program flow. The net result, when rendering a single bilinear filtered textured triangle at 640x480 is approximately 22-24 fps when the triangle covers approximately 1/3 of the screen. VTune tells me that my latest hotspot is the bilinear sample function, and there is not a whole lot going on in there other than looking up some memory and combining it all together.

I would like to eventually perform some SSE2 optimizations, in particular on the rasterizer. This would be my first venture into such a beast, and would be a great learning experience. I have wanted to add some form of SIMD support to my vector/matrix operations for a while now anyways.

However, the software rendering project is going to be ramping down. I have a couple other projects that I have been kicking around in my head that are just about ready to start, and my free time is very limited right now. I should get some news in the next couple days regarding a couple of proposals that I submitted last month, so my free time schedule is going to be either completely empty or a little more open in the coming days.

I still haven't decided if I will attempt to write a software rendering article or not. It would be fun I'm sure, but I don't know if I can add enough material to make it worth while. We'll have to see how that goes - usually if I am going to write it, inspiration will strike me and I'll just start writing. We'll see how it all works out...
