Yes, but the management of all the state and the rasterization of it makes it both CPU and memory bandwidth intensive. Some of this is OpenGL's fault and some of it is Mesa's fault. You really need either 3D hardware or no need to render in realtime to use Mesa. This is true on desktop machines and the laptops. People have definitely done 3D rendering with less powerful hardware, though, so dropping some features and writing one's own renderer (or finding one that cares more about speed than OpenGL correctness or quality than Mesa) might be possible. --ryan. _______________________________________________ Devel mailing list [email protected] http://mailman.laptop.org/mailman/listinfo/devel
