Shader Week, Day 2
First of all: installed Visual Studio Extension to get some basic autocompletion when writing shader code. An improvement!
Second, was looking for how the sampling of pixels was working and found CG documentation:
http://http.developer.nvidia.com/Cg/index_stdlib.html (look for tex2D-function)
Apart from that, I finished off the tutorial from yesterday (interpolated colors into the rendered texture), and then proceeded with applying a shader to the camera for full screen effects - using OnRenderImage(src, dest) and Graphics.Blit(src, dest, material).
Finally played a bit by adding a displacement map, distorting the entire screen. Simple stuff, but still funny!
