Real Time Radiosity on GPU
|
Hi,
My first intention was to find a technique to render radiosity offline with a GPU, faster than using Hemicubes.
I found one that I achieved to run in realtime on a small scene (no PRT or any precomputed stuff here)

Your technique somehow reminds of the "High-Quality Global Illumination rendering Using Rasterization" article from GPU Gems 2 (the depth peeling stuff...) but I have never really read it thoroughly. How does your... |

Yes. Sorry I didn't know for 6200. Apparently, those cards don't support blending nor filtering on ABGR16F format.

Very impressive work and thanks for sharing!
I noticed some bilinear artifacts in the lighting, do you think these could be hidden better be manually gaussian blurring the radiance texture instead of using a low... |
