I recently played Freelancer again. While I where playing I had a idea how to create a trail effect with a particle system using a vertex shader.

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
