Re: 3D Vector Type Line-Drawing Program
Hi, I am not sure, if that is, what your looking for, but with 'salome' you able to produce 3D drawings with an GUI or using a python script.

Re: 3D Vector Type Line-Drawing Program
I'm looking for a program to do line-drawings in 3d, with output to postscript or svg or pdf, etc. I would like to describe a scene with certain 1-3d elements oriented in 3d space with dashed or colored lines and filled or transparent surfaces (or maybe semitransparent). For high quality line drawings using Python you have PyX [1]. Unfortunately it does not come with a 3D library. You probably have too look elsewere for 3D vector drawings. Some places to look are: - Asymptote [2] - Sketch [3]. A small, simple system for producing line drawings of two- or three-dimensional solid objects and scenes. Sketch generates PSTricks code for LaTeX. Both Asymptote and Sketch requires TeX/LaTeX for typesetting labels and such. Sketch is probably the closest to what you are looking for. See [4] for an example of what kind of graphics it can create.

3D Vector Type Line-Drawing Program
hi, Take a look at VPython -- easy to start, 3-D display (wall-eye / cross-eye) easy to run on. I really like VPython because of how easy it is to use once you are familiar with it. Is there a way to have the display show a wire frame image instead of shaded shapes? And with or without hidden line removal? i'm goind the same. I looked to vpython, but i can't make it go with wxpython. So i make a slightly different question. There is a library that fits well with wxpython that have features similar to vpython? thanks, nelson -- http://mail.python.org/mailman/listinfo/python-list

The distinction would be whether you actually build the objects. Certainly for something like this you would be working with something like a faces object rather than a fully 3-D object.

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.
