(...) Your expectation is certainly justified. I don't know what the driver architecture is on the Mac, but I suspect that the video hardware manufacturers are responsible for the OpenGL implementation for their own hardware, just like on the PC. If (...) (21 years ago, 17-May-04, to lugnet.cad.dev.mac)

(...) Travis Having done some experiments and research over the last couple of days, it seems that to get very fast drawing in OpenGL generally, vertex arrays are necessary. OpenGL has specific commands such as glBufferDataARB that will explicitly (...) (21 years ago, 20-May-04, to lugnet.cad.dev.mac)

(...) Just as a note, I found that Vertex Buffer Objects (VBOs) would crash my ATI card in Windows when used inside a display list. As far as I can tell, this isn't supposed to happen. Regular vertex arrays work fine inside a display list. General (...) (21 years ago, 21-May-04, to lugnet.cad.dev.mac)

(...) Yeah, watch out for that software rendering on the Mac. It sneeks up on you. I know it can switch you over while your program is running, but I don't know what causes it to happen other than resizing a window. You might want to query it about (...)

(...) Actually, the same thing can happen in Windows if you resize a window too big (say 1600x1200) on an older video card. However, I'm not sure you can tell that it has switched to software mode on Windows, because as far as I know it is still (...) (21 years ago, 21-May-04, to lugnet.cad.dev.mac)
