Parallax Occlusion Shader (GLSL)

Posted on May 28, 2008 by Benjamin Thaut

Sample Picture

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

Download:

parallax.rfx (Rendermonkey 1.80)
