Final Gather

Posted: October 31, 2011 in RayTracing

Some early renders using my Final Gather implementation. The first shot is of just the indirect illumination with no interpolating. The second shot is with interpolation of 3 points, and the third shot with 10 points. The final shot is with the direct illumination too. You can see the FG points Im sampling in the the top viewport (the green points), which currently are uniformaly sampled at across the viewing plane (using a ration of 1/5 to pixels in the shots below). Unfortunatly, even with many FG points and a lot of interpolation the results still contain noticeable low frequency noise. Hopefully this will be reduced by importance sampling the FG points as opposed to unformly distributing them.
