Hey, I am just looking for a cheap but cool looking four or five tap shadow map filter. So far I thought about the following: - four-tap Poisson Disk (untested, but should not really make a huge difference) - orienting the four taps about 45 degree rotated, so that the fetches are a bit rotated (does not really improve anything) - rotating a four tap filter all the time with a fifth random look-up texture that holds values to construct a rotation matrix (untested ... only tried this with a 8-tap Poisson Disk) - four tap filter with a fifth tap for a noise texture (untested) If you have used any of these, I would be interested in your opinion. - Wolf

Hey this is cool ... thanks a lot. Looks better indeed. Now I want to bring in some noise. Anyone has a good idea on how to add noise the best way? I need to create a noise texture, this texture should have two channels that keep the noise to distort the texture fetch by multiplying/adding (?) them to the texture coordinates used to fetch the texture.
