I’m trying to find a global illumination solution for my application, and I need it to be fast.
So I tried to get direct illumination into the light map by sampling a shadow map.
The light map’s resolution is pretty low, and caused the problems of aliasing ( in my case, it’s 128 * 128 for the ground).
Is there any way to improve this?
Thank you all for reading my post, and sorry for my poor English.
