OpenGL Presentation at Siggraph Available

Visigothe writes "Siggraph has made available the Apple Quartz Extreme Demonstration PDF. The PDF has an overview of some interesting Quartz Extreme features, including the OpenGL calls that are made, as well as the new OpenGL extensions that Apple created for their upcoming Jaguar release. This is going to be a very interesting window system indeed!"

Re:OpenGL contributions

[inkfox]

The .pdf didn't indicate (it's a PR/marketing piece,) so I'm assuming that the new extensions will be contributed to the OpenGL folks for inclusion. Is this correct? If so, a very nice contribution by the Apple folks!

The wording is a little deceptive.

Most of these are extensions already existing for Windows and other OpenGL ports. NVidia example. ATI example. What they're basically saying is that the Mac drivers are caught up, and/or use of the extension is new to Jaguar's version of the Quartz engine.

There are a few Apple-specific extensions in there, but they're very specially purposed to Quartz' preferred data formats. Essentially, they're just a way to reduce the portability of the system (restricted pixel formats) in favor of some speed boosts, which is a pretty fair tradeoff if you're a company like Apple who only deals with a pocketful of vendors who make special concessions. You wouldn't want these back in OpenGL main.

There's some damned fine engineering going on at Apple, as always. But there's also the familiar nice spin, though. I wish they'd keep that much out of the technical presentations, or at least would more clearly mark it as such.
