Shader Optimization.
I was playing with the shader and wondered if it could be optimized. Lets start with the standard Shader float2 HmdWarp(float2 in01) { float2 theta = (in01 - LensCenter) * ScaleIn; // ...
Nicely done lazydodo. Back before programmable shaders it was all about using textures as functions (look up tables). There's still value to such techniques. :)
