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)
I wanted to... |

So are you actually doing a total of 1 pass with 16 directions or 16 passes with 16 directions?
How are you doing the grouped render, something like a matrix palette of 16 different viewing directions?

The 6200 doesn't support linear filtering on fp16. Is that a concern for ezbez?
Yes. Sorry I didn't know for 6200. Apparently, those cards don't support blending nor filtering on ABGR16F format.
The problem... |

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... |
