Case study III - Progressive Radiosity Graphic system implementing simple version of progressive radiosity can work by the next schedule. GlobalShader gets the position of light sources. These are used as starting surfaces for energy distribution. In the next step GlobalShader takes visible objects from Explorer , computes form factors and deposits shooted energy to patches. Patches with deposited energy are stored locally and they are used in the next iteration step.
Next steps are similar to flat model.
Progressive radiosity communication protocol 6. But the next travels through already mapped area should be faster and more effective. Our idea is to use the above described situation as paradigm for the dynamic scene with global rendering. We have already proposed and implemented the model in which explorer is looking at map during his travel in space. It offers many possibilities to experiment with different space sorting structures, bounding volumes speed-up techniques etc.
