capture NSOpenGL (Cocoa) onto a QuickTime frame

30 Apr 2001

      Does anyone know a good way to capture the frame from an

NSOpenGL to a QuickTime file?
...
From the NSOpenGL side (which is named myOpenGLView), I have
NSBitmapImageRep *bitmap;

	bitmap = [[NSBitmapImageRep alloc]
initWithFocusedViewRect:[myOpenGLView 		bounds]];

	unsigned char *pixmap = [bitmap bitmapData];

assuming the the openGL scene is already rendered in the window.

In a code from pre-Cocoa days, I used to take the PixMapHandle of the
Gworld in which

I create my scene,

PixMapHandle pmh = GetPortPixMap(theGWorld);

LockPixels(pmh);

..... vanila QT routines (such as GetMaxCompressionSize, etc follow)

Now, how do I use the pixmap data in place of the usual pmh of the
GWorld?

Does any one know how to make this work or even a better way?

Thanks,
