First and foremost, it is a 3D engine. Then I went in an identified some missing things that would be good for 2D and hacked them in. The result is that some 2D things require a bit more setup than you'd be used to because basically, you're just doing a 3D thing with some of the features disabled. For instance, a 2D bitblt is just a 3D texture operation without any distortion (or with, if you prefer). This isn't a new idea. The Permedia 2 had a unified 2D/3D engine. In later models, they separated it out a bit for performance (bus bandwidth) reasons. We'll eventually do something similar. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
