Re: Missing functions on MacOSX?

Hi Mike,

Thanks so much again for all your help.

I've run your script and the first thing I had to do was comment out the NV import and function call as I got an ImportError saying OpenGl.GL.NV has no module named draw_instanced. The good news is once I comment this out, the example runs and I get the following:

glDrawArraysInstanced False
glDrawArraysInstancedARB True
glDrawArraysInstancedEXT False
<OpenGL.extensions.glDrawArraysInstanced object at 0x10510a248> True

Which I guess means its managing to use the ARB version, which is excellent. All I need to do now is work out how to configure this when using Qt as the host...

Thanks again,
Rob

Hi Guys,

Further to my previous email, I have now re-installed PyOpenGL and can
call the glInitDrawInstanced* functions for ARB and EXT without them seg
faulting but they both return False. Is it a case of importing the correct
modules to get ARB/EXT methods initialised and if so, which modules? Any
thoughts or advice would be greatly appreciated.
I've attached a module that, using GLUT as the host, prints out which of
the various alternates is available.  The glInit* functions aren't
really necessary with modern PyOpenGL, they should still work, but they
just do an "is this extension in glGetString( GL_EXTENSIONS )" test.
The sample also shows how to create an OpenGL.extensions.alternate that
will call the first of the functions available on the machine.

Hope that helps,
Mike
