[PyOpenGL-Users] glDrawPixels source data

[Gavin B. <ga...@an...>]

Hi,

I am using PyOpenGL (with wxPython) to do some image processing.  We are
processing the data in a C module and returning this to Python to draw
with glDrawPixels() via PyString_FromStringAndSize(...).  This works
fine, but is inefficient as it is copying every single frame.

Ideally we would like to be able to use a buffer object to simply
wrapper the memory, using PyBuffer_FromMemory() but this doesn't work
(it segfaults).

So is there a way I can pass a Buffer object to glDrawPixels?

If not, how might one go about adding this sort of support?  I am
prepared to have a go at adding this support if I can.

Thanks,
