An Inkscape plugin for rendering 3D polyhedra with vertex colours
This plugin for the great Inkscape vector graphics program permits rendering 3D polyhedra and meshes in Wavefront OBJ format. It is based on a similar plugin but offers the possibility to use vertex colours that are included in the mesh. This makes the plugin suitable when additional information such as vertex quality or curvature have to be visualized.
The plugin was originally developed to obtain publication-quality vector graphics for my dissertation. Please refer to this blog post for more details.

You can set different viewing options, such as the camera position, including some transformations, and other styles as well—these are taken as-is from the original plugin. It may be useful to experiment with different settings for the stroke width of the input mesh, in particular when mesh scales are small.
This is how the example data files should look like:
