Occlusion Query

Rats, this is an opengl 2.0 thing right?

Bought the opengl 2 programming guide and wanted to use the occlusion stuff. Behold, I'm on a mac and cannot do anything.

ATI 9800 on a new g5. Looks like opengl 1.5 on the driver. Latest xcode tools.

Does apple want direct x to win or something? I can't figure out the lagging. Or is it the video card manufacturers like ATI? Never really liked ATI.

Poop.

I'm afraid I do not understand your request, however GL_ARB_occlusion_query is part of OpenGL 1.5 specification, and a G5 w ATI 9800 is able to manage this extension.

Cyril.

Hmm, looks like your right.

Thank you sir.

OpenGL uses layered extensions to expose functionality, so you can not figure out what a given video card can do just by looking at GL_VERSION. See Understanding and Detecting OpenGL Functionality (http://developer.apple.com/technotes/tn2002/tn2080.html) for an overview.

This GL Info table (http://homepage.mac.com/arekkusu/bugs/GLInfo.html) may also be useful to see what features are available on each video card on Mac OS X.
