RE: [Visualpython-users] How to print ?

[David S. <dsc...@vy...>]

For printing graphs, the best thing would probably be to bring in another
graphing or drawing package that supports high-quality postscript output,
and write code to convert a visual.graph into that package's conception of a
graph.

"Direct" high-resolution printing of 3D scenes could be done by modifying
cvisual to point its OpenGL context at a high-resolution WMF in memory and
rendering a frame.  That approach obviously requires some C++, OpenGL, and
Windows programming skills.

The POV approach also doesn't sound bad, although I haven't tried it.  Maybe
for convenience povexport.py should be able to run POVray through
os.system()?
