[vtkusers] Mac offscreen drawing

[Paul Schmiedge]

Greetings,

I've been scouring the archives for this list, but I can't seem to find 
a way to accomplish my goal - Does anyone know how to accomplish 
batch-oriented offscreen rendering on OSX (10.3)?  I'm not using 
Objective C, so Cocoa is not an option, but I am willing to use Carbon 
or Apple's X11 if I have to.  I've experimented with both so far, but 
the call to vtkXOpenGLRenderWindow::SetOffScreenRendering() results in 
an error for X11 (bad memory access), and there seems to be no effect 
when the same call is made on any other window type.  I've also studied 
the Tcl example for Mangled Mesa, but I'm not sure if that's an option 
for OSX, or how I would go about setting it up on this platform.

Any thoughts would be appreciated.

Thanks in advance,

Paul S.
