[Pythonmac-SIG] [OT] Quicktime/Buffer API

[Andrew Straw]

You may want to investigate the new array interface:

http://numeric.scipy.org/array_interface.html

It's meant to deal with this situation.

Travis Oliphant also has plans to build a C version of this. For now, if 
you need to do it in C, you'll have to use the Python-C API and 
manipulate the Python objects.

I don't think PyOpenGL supports the array interface, but you could 
either: 1) make it support such or 2) wrap your own call to 
glTex(Sub)Image to deal with the data...

Do you have any plans to release the code you're writing?

Cheers!
Andrew
