I said I wasn't going to do anything more to the renderer right now. I lied. (We will stop enhancing the truth in 3...2... *BZZT*)|
Dropped in variance shadow maps. Took me all of half an hour, and it improves shadow quality tremendously. What a clever idea. No blur pass yet, because I'm really a lazy sod, but even with just plain linear filtering you get good results.
I have to figure out why the hell my bias in the variance term is so fucking high, though, and I also have to figure out a way to try and clean up artifacts on the edges of 'sharp' pieces of geometry that are coplanar to the light. (i.e. the tops of crates and things) Nothing is perfect, but it's not bad...
