Convolution sans Cg

nVidia only offers a cG solution for convolution. We are on LINUX & OSX with nVidia. Is there an equivalent project we missed? THANK YOU!! :confused:

CG runs on Linux and AFAIK on OSX, so I do not see the problem. Of course you can use GLSL, too. The first google hit looks promising:

Ahhh, where have I been? I want to find the slashdot article that tells of nVidia’s porting of what was thought to be a Microsoft only lib!! cG on all platforms? Man have I been out of it! THANK YOU!

Oh, I see. Use OGL shader, will that work on ATI cards? Does the Shader Addision-Wesley book have any stuff on Singal Processing in it? THANK YOU
