Is there any software that will take a 3d model (in any format) and allow you to render it as a 2D vector image (preferable as either an .SVG or .PDF)?
My intention is to render LEGO building instructions this way. While there are many tools that let you view them or generate nice, rasterized output, I'd really like to be able to generate vectorized output. Textures are not needed, and hidden line removal may not be needed.
I could use a tool that works on any platform (although my preference is OS X, Linux, then Windows). Open source is preferred.
If no one knows of a tool that does this, does anyone have a good recommendation of something to hack on and add a feature to output via Cairo?
