Freestyle is in Blender! Starting with version 2.67, Blender ships with Freestyle.
Get Blender and give it a try.
Congratulations to Tamito Kajiyama for pushing the integration to
the finish line, it's been an incredible work. You can see the work that was accomplished
and the latest Freestyle/Blender updates here:
Congratulations as well to
Maxime Curioni who made the integration possible at all, solving some incredibly
difficult problems (against many common beliefs, the fact that Freestyle and
Blender were both using Python didn't make the integration easier, on the contrary).
Finally, a big thanks to the Blender artists community who has been supporting
the project from the start and especially the early adventurous adopters of Freestyle.
A lot of work remains to be done to get Freestyle to a fully production-ready
state. We are hopeful that having Freestyle in Blender's mainline will encourage
more developers to get involved.
We will keep the standalone version of Freestyle available here, but we encourage
artists to use the Blender version.
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
