Hi all, I was wondering if data can be passed up the pipeline in today''s DX8 hardware? (speceifically after data has been transformed by a vertex shader, can it be passed back to main memory or a CPU reg?) Thanks, Victor

in short: no.

basically the hardware is designed to render the data to the screen. reading from vram is exceedingly slow (easily turns frames per second to seconds per frame). instead you would transform the vertices by the cpu if you need the transformed vertices for something.
