Re: [PyOpenGL-Users] Creating a postscript image of a scene : how do I use openglutil ?

[Mike C. F. <mcf...@ro...>]

If anyone's interested the GLP library is an (LGPL) C++ lib to do OpenGL 
-> postscript:

    http://www.easysw.com/~mike/opengl/index.html

it honestly doesn't seem particuarly complex, it uses the feedback 
buffer, and apparently does some culling of the results to eliminate 
massive overdraw. 

Similar-looking C lib for the same purpose (also LGPL):

    http://www.geuz.org/gl2ps/

apparently had a Python wrapper at some point in time, though it doesn't 
appear to be available any more (Toby?)  All in all this looks like the 
most mature of the solutions (for instance it appears able to deal with 
intersection polygons, though if I'm reading right it may generate 
striated results for smooth-shaded polygons.

There's another variant on the same approach here:

Enjoy,
Mike
