I am putting the finishing touches on a 2D game. I started out with Quartz/CA graphics, and while the game was simple enough, I was simply unable to get anything near decent performance. I learned enough OpenGL [ES] in about 15 hours (all from top hits on googling "opengl 2d sample code" [I think]) to outperform the old code by probably an order of magnitude. Just for grins, I quadrupled the number of objects in my scene (to over several hundred), and I'm still getting 60fps with no problem (I'm actually limiting my frame rate to that, so I'm sure it would be much higher). My scenes are rather simple (no lighting, "glowing", or anything), but still...a *remarkable* difference. I decided to leave in a few CA animations because they were so simple, and I really want to ship RSN; this was my first foray into OpenGL, and I'm now a believer. randy_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
