Hmm. I always understood FBOs to be an improved (and portable) version of pbuffers, since you have to use platform-specific stuff to create a pbuffer (well, OSG does it for you, but it still has to use wgl stuff). > In any case, to use FBOs you need a context, one way or the other. I'm going to have to go back and read up on my reference material again. I thought for sure there was supposed to be a way to use FBOs without pbuffers. > Hope this helps, Thanks for the info. > J-S -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.
