[PD] exporting opengl as vector

[Py Fave]

that's what i was thinking too...

i remember a long  time ago :-)
there was a "fake driver" for graphics cards made for ripping 3d game
graphics.(on directx windows IIRC)

does software emulator for GPU exists?debugger?
on linux or windows?

or a (not too hard) way to access the GPU's memory and dump it??
and collect/reuse this data?

Thanks cyrille!

Cheers,

py
