Hi, I admit that I did not do any performance analysis on Mac, but still this is hard to believe... what exactly has been tested, on what machines using what GPUs ( and thus drivers )? Anyway, an indexed geometry base class would still be nice to have. And yes, this would be a subclass of G3DGeometry. cheers, -Phil On Monday, July 8, 2002, at 08:26 PM, Brent Gulanowski wrote: > Hi, > > I posted a question on the iDevGames forums about vertex submission > paths and relative speed, and was surprised to learn that (on Macs at > least) glDrawElements() is notably faster (5-7%) than glDrawArrays() in > most systems.
