Re: OpenGL development on FreeBSD

Are there any OpenGL developers out there that can point me to FAQs or docs that are necessary to work in this environment? Many TIA - Regards, Doug Greetings! Having hacked some OpenGL on FreeBSD myself, I found www.opengl.org to be helpful (the obvious one, perhaps), as well as NeHe's tutorials over on nehe.gamedev.net Basically, any stuff that's valid for Linux, is also valid for FreeBSD. The OpenGL API is identical (and comes installed with X), the only thing that might be different is the placement of libraries and headers, but this is handled during compile-time anyways. The other thing is hardware acceleration. I'm fuzzy on this, but my impression is that this is somewhat non-existent on FreeBSD. The only exception quite possibly being the NVIDIA drivers. If he's porting from Linux, my guess is that he's got a fairly easy job ahead of him. If he's porting from Windows, that's going to pose a lot more work. Also, he'll need to use one of the appropriate libraries (GLUT or SDL) unless he wants to code directly atop libX11 *shudder*.

Kilgard's `OpenGL programming for the X Window System' also makes a good start if you prefer dead tree documentation, although the Motif stuff is not that useful these days, but the basics remain the same.

I'd say FreeBSD is almost on par with Linux with regards to 3D hardware acceleration, the exception being high end ATi cards which only work with ATi's closed source drivers. All cards supported by the DRI open source drivers work fine in FreeBSD. I haven't noticed performance difference between Arch Linux and FreeBSD 5.3 when it comes to OpenGL apps. Ironically, my little SDL benchmarks performed better on the BSDs, even when one of the CPUs was busy. Could be a scheduler side effect, not sure.

All modern toolkits allow integration with OpenGL these days, be it SDL or GTK+/Qt if you need something more feature rich. I see little reason not to use them.

I see little reason not to use them. Just my $0.02 I'll most definitely keep that in mind. I remember from trying out GLUT that it is limited. SDL is what I've been using, but if QT and GTK+ also have support for OpenGL, well, that's grand! :-D -Henrik ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
