...It's NOT EASY to use- so don't bother if you aren't willing to do a bit of tinkering with it... but for anyone interested in DEVELOPING NPR EFX for Daz Studio- should REALLY take a look at this...

"Freestyle is a software for Non-Photorealistic Line Drawing rendering from 3D scenes. It is designed as a programmable interface to allow maximum control over the style of the final drawing: the user "programs" how the silhouettes and other feature lines from the 3D model should be turned into stylized strokes using a set of programmable operators dedicated to style description. This programmable approach, inspired by the shading languages available in photorealistic renderers such as Pixar's RenderMan, overcomes the limitations of integrated software with access to a limited number of parameters and permits the design of an infinite variety of rich and complex styles. The system currently focuses on pure line drawing as a first step. The style description language is Python augmented with our set of operators.
Freestyle was developed in the framework of a research project dedicated to the study of stylized line drawing rendering from 3D scenes. Details about this research can be found at:
