Parallax Occlusion Shader (GLSL)
May 28th, 2008
I wrote a parallax occlusion Shader in Rendermonkey. Unfortunately due to the fact that the devartives in flow control elements are undefined, the ARB_texture_lod extension would be neccesarry for this shader in glsl with shadermodel 3.0. Until this extension is released EXT_gpu_shader4 has to be used as replacement. So this shader only runs on gForce 8+ cards. Ati doesn't support that extension yet.
Needed Extensions:
- EXT_gpu_shader4

Hi man!
I’ve a question about your shader. Where did you find the way to calculate the mipmap level? Can you link me some site where can I find the theory behind this calculations?
Thank you!
