Hunter's comment

Freestyle is a rendering software for non-photorealistic line drawing. which provides 3D senses. Its interface is programmable so it will allow to its user to have full control over drawing styles. For each drawing style, it provides the style modules, python files and their dependencies too. Freestyle is quite tricky so the only pro can take advantage of this amazing software ;)
