The title of the post is kind > of misleading. > At one point I created a gl2ps wrapper for use with PyOpenGL, that, combined with any of the PyOpenGL-based renderers would allow much of what you're describing, though IIRC it didn't properly support transparent or textured surfaces. You could probably recreate the wrapper using ctypes in a few hours and then hook it up in a few more.
I believe there are similar OpenGL-to-SVG libraries here and there, you could likely hook one of them up to get a reasonable result that would support more graphics features (maybe). Generally what you get out of these things, however, is a quite fragmented view of your objects (that is, you get the triangles that would be rendered). That *can* be coded around, but generally people are either focused on making it look good or making it editable. Good luck, Mike -- ________________________________________________ Mike C.
