OpenGL 3 and Lion question...

We cannot disclose even this.

However the answer is in the Mac OS X Technology Overview of the Lion Developer Library. Specifically look in Media Layer > Media Layer Frameworks > OpenGL within that overview guide.

I hope that doesn't contravine my NDA.

 

MacRumors reported a while ago that it supports 3.2.

 

I'm not under NDA since I'm not part of the Mac Dev program. A simple Google search turned up the code to get a OpenGL 3.2 context on Lion :

Code:

#include <OpenGL/OpenGL.h>
#include <OpenGL/gl3.h>
#include <stdio.h>

int main(int argc, char **argv)
{
     CGLContextObj ctx;
     CGLPixelFormatObj pix;
     GLint npix;
     CGLPixelFormatAttribute attribs[] = {
               kCGLPFAOpenGLProfile, kCGLOGLPVersion_3_2_Core,
               0
     };

CGLChoosePixelFormat(attribs, &pix, &npix);
     CGLCreateContext(pix, NULL, &ctx);
     CGLSetCurrentContext(ctx);

printf("%s %s\n", glGetString(GL_RENDERER), glGetString(GL_VERSION));

return 0;
}

This was posted to some Macrumors discussion a while back.

 

Lion and the Lion developer documentation are only available via the Mac dev program. That makes it Apple Confidential Information according to clause 2.2 of the Mac dev program agreement (10/20/2010). A disclosure (or discussion) by third-parties in contravention to the agreement don't lessen the force of the agreement. Or am I wrong?

 

Yes.

Because by definition it is not an agreement unless both parties have entered into it. Therefore if you are not a member of the Mac Dev program you are not subject to the NDA.

 

I have never agreed to that so yes you're wrong.

 

External USB/FireWire drives are cheap ..., install to one and boot from it leaving your internal drive untouched.

 

I see now. It's not that it's not under the NDA clause of the Mac Dev agreement. It is. It's that you're not part of the Mac Dev program. So you are free to talk, while I am not.

 

It shouldn't as its a publicly available document provided by the contractor.

 

I can see some advantage to learning OpenGL 3 on Lion (since you have a full OpenGL 3 implementation available which will simply disallow deprecated functions from being used) but do remember that Mac OS X 10.6 does have most of OpenGL 3 available as extensions.
