Hi
These are used used by 3D driver back depth/stencil buffers and texture memory. This memory is reserved so it wont get overwritten by 2D driver. It is used by means of RADEONInfoRec::frontOffset, RADEONInfoRec::backOffset etc... It can be freed if no 3D is active. BTW: As I'am working on stereo now I need to allocate additional buffers for left eye buffers. Currently I allocate them whenever TransitionTo3D is called, but I think it would be quite useful if I would add TransitionToStereo/Mono functions and allocate/free them then. I looked at DRICreatedrawable code but I have no clue how to check whether drawable is stereo (if it does make sense). I think I can do it by checking Visual, but no clue how to get it. Can someone give me some clues. -- Jacek Rosik <[EMAIL PROTECTED]> ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
