From Eurographics 2007 talk "Realtime Global Illumination for Next Generation Games", scene with lots of indirect light in Sponza atrium. Lighting was computed in real time by standard gaming PC. Thanks to Marko Dabrovic for scene. More at http://lightsprint.com

  • Precalculated Radiance Transfer.

  • Unlike PRT, this supports arbitrarily moving local lights and local objects, see it in Lightsmark (executable demo).

  • There seems to be sort of 'stepping' on the Indirect Illumination looks as like it's calculated for a certain number of frames. Looks odd as the Direct Illumination is (obviously) frame by frame.

  • Indirect light is recalculated in each frame based on direct light in sampling points. What you see is probably that direct light hits many new sampling points at once. Newer versions use better placement of sampling points.

  • The shadows are too hard, imo. Did u use any precalculation?

  • Yes, optional precalc of static visibility was enabled, it increases fps while lights and objects can still freely move. It can run without precalc too.
