Re: [Gnu3dkit-discuss] DrawElements faster than DrawArrays

[Philippe C.D. Robert]

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
