Detected accelerated 3D

I was wondering if there was a quick trick to check whether
accelerated 3D is available on a particular computer? I’m not
interested in actually using it, I’d like to gather some statistics
context briefly, I guess I’ll do what I have to do. I’m not averse to
using platform-specific calls for Linux, Windows and Mac OS X, that’s
pretty much all we’ve got, so that’d cover it fine.

Thanks!from my users first… Although, if what I have to do is setting up a

I’d just try using wglCreateContext() (on Windows, or whatever its equivalent is for Linux and OSX) and see if it returns a valid result.>----- Original Message ----

This would probably get me a software renderer (which wouldn’t have 3D
acceleration), no? The Linux equivalent would, in any case…On Tue, Jun 17, 2008 at 11:14 PM, Mason Wheeler wrote:

Good point. I did a bit of looking and found a trick that will work, but it’s apparently Windows-only. See http://www.opengl.org/resources/faq/technical/mswindows.htm#0020 for the details. Anyone know equivalent tricks on other platforms?>----- Original Message ----

Check the return value of SDL_GL_SetAttribute(
SDL_GL_ACCELERATED_VISUAL, 1 ). Note
http://bugzilla.icculus.org/show_bug.cgi?id=3526 though.

Actually, not the return value; I think you’ll actually need to call
SDL_SetVideoMode…
