good morning, i'm trying to map a matrix in gpu memory using texture mapping to make some operations.. , i've read something in this tutorial http://www.mathematik.uni-dortmund.de/~goeddeke/gpgpu/tutorial.html
. my problem is that i can't use rgb values because i need to mantain my values order, if i use a rgb vector, how can I maintain the order when i'll copy back to disc the matrix ?

hi,

I don't totally understand your problem, but I think that this post (http://www.m3xbox.com/GPU_blog/?p=9) and maybe this other one (http://www.m3xbox.com/GPU_blog/?p=6) from my blog could help you.
