Light Scatter

GLSL : Graphic card bug ? QC bug ? Bad code ?

Hi !

I've been fascinated for months with toneburst CI implementation of Light Scattering, from GPU Gems. So I decided to try to make a GLSL Shader with it. In fact, while googling I found some simple GLSL code coming directly from GPU Gems (http://stackoverflow.com/questions/13489703/sfml-2-0-glsl-volumetric-lig...).

But, it is very buggy, and it looks like a graphic card bug, or maybe I'm not dealing with the texture properly, or... could it be a QC bug ? (I'm on 10.8)

I would be extremely grateful for any advice on this :-)

Thanks.

Ben
