Re: [GEM-dev] Way to get gemframebuffer back onto main memory for pix_ operations?

Hi Chris,

I figured that may be the only way, to put the video on the gfx card and do all the analysis as a shader.

This is the best way to go in the long term, but I don't have time to implement the video analysis as a shader (ie pix_multiblob).

Unless someone already has implemented pix_add and pix_multiblob in a shader?

Thanks, b.

This would be a good use for a shader. Much faster to do that way and a good way to get into GLSL too.

Hey all,

I'm rendering data into a framebuffer, but want to be able to
pix_add that texture with a live video input.

How can I get a gemframebuffer image from texture space into pix_
space???

Thanks,
B. Bogart
