matrices and graphic cards

[akhar]

I was just wandering if it is possible to use the cpu power on a 3D
accelerated graphic's card to boost a script performances? I have an image
manipulation script that converts the image into 3 matrrices and then
performs some operations on it and it takes about 20 seconds of execution
per image, and knowing that 3d gaming can get a lot of frames per second
well.... I was hoping it might help. If it is possible how can I achieve
this? I am using PIL and Numeric.
