I looked at that link some time ago when converting to X11, it was kind of helpful but I have some better PDF docs on my work/private drives. I'll dig em out. I'm actually starting to learn/write my own shaders at the moment as I want to convert some DX9 into Dx11 format that were useful in FPSC. It's just a case of understanding the graphics rendering pipeline etc. It's a lot of fun seeing some results. I'm also playing around with FFTW libs for various texture manipulation. Will upload as soon as I find the good tuts/pdf's.
