mightcouldb1 Posted July 11, 2009 Share Posted July 11, 2009 I have done a few renders using the various pixel filters and blackman seems the one to choose. I wish that I could see a curve graph similar to this one. Can anyone break these down for me? It seems as to me that this is the order from most sharpest to least: sinc catmul-rom hanning blackman gauss Am I correct? Also, what pixel filter(s) is commonly used in production? Thanks!

DaJuice Posted July 11, 2009 Share Posted July 11, 2009 I usually use either the default gaussian or blackman filter. Blackman is nice if you want a clean, crisp look. I personally avoid catmull-rom and sinc, because of edge-enhancement. Hanning was the softest I thought, but I'm not sure.. Quote Link to comment Share on other sites More sharing options...

rendertan Posted July 18, 2009 Share Posted July 18, 2009 There's a very interesting presentation at http://www.renderman.org concerning filter types in PRMan and the different combination of filter types, samples, and shading rates. You might want to take a look at it, i found it a great reference overall: Filtering in PRman Quote Link to comment Share on other sites More sharing options...
kensonuken Posted July 18, 2009 Share Posted July 18, 2009 which one looks best for fur I tried using Triangle filter with 3x3 its looking good. But thought it can still be better any recommendations for fur..... Quote Link to comment Share on other sites More sharing options...
abvfx Posted July 19, 2009 Share Posted July 19, 2009 i use triangle when rendering fur, it may sound obvious but try upping the samples. Quote Link to comment Share on other sites More sharing options...
