PVR hardware flip

Post by Newbie »

Hi everybody,

I want to know if it is possible to use PVR hardware only (no SH4 bytes processing or intermediate texture caching) to horizontal flip a texture stored in video ram and draw it straight on screen.

Thanks for help.

Swap the U coordinates on your vertices such that the right hand side is 0.0 and the left hand side is 1.0 (assuming that you're drawing the entire texture -- otherwise, adjust as necessary if you're doing something like a sprite sheet).
