Trying glrad on a Mac...

Doesn't seem to work very well; no edges, and surfaces are either dark or light. Is this how it's supposed to work? Or is there some platform-specific problem?

Hi Randolph,

I've had problems with glrad on various platforms as well, but I've no idea how to fix it. I'm not much of an OpenGL programmer, and the compatibility issues between implementations are considerable. Anyone who wants to take this on, I'd be more than happy to answer questions about what it's supposed to be doing, etc.

I just tried it on 10.4.11. The geometry is shaded as I would have
expected. The movement controls via mouse are pretty much unusable,
though.

I am still on R3.8 here and I think I downloaded the binaries instead
of rolling my own.

Do you use OS X 10.4 or 10.5 (Leopard)? The graphic system changed
significantly between the two ("Core Graphics") and plain old OpenGL
might have suffered a bit.

Thanks, Greg. I'll think about that one. This kind of issue is part of why I'm asking about platforms. I can see chasing down OpenGL issues for one or two platforms; six would be insane.

I'm on 10.5--might be the problem. Maybe if I rebuilt from source it would be OK

Addressing navigation is a possible project...
