'''Freestyle''' is a [free](/source/Free_software), [open source](/source/Open-source_software) renderer for [non-photorealistic](/source/Non-photorealistic_rendering) line drawing from 3D scenes.

== Model ==
The program uses a [shader script](/source/shader) model inspired by the [RenderMan Shading Language](/source/RenderMan_Shading_Language), allowing different shading styles to be written as a script that's interpreted at the render time. The different rendering styles are based on "style modules" that are written in [Python programming language](/source/Python_(programming_language)).<ref>{{cite web|title=Programmable Style for NPR Line Drawing|url=http://maverick.inria.fr/Publications/2004/GTDS04/|publisher=ACM Press|accessdate=23 June 2013|author1=Stéphane Grabli |author2=Emmanuel Turquin |author3=Frédo Durand |author4=François Sillion |date=June 2004}}</ref>

The stand-alone program, which uses [OpenGL](/source/OpenGL) and the [Qt](/source/Qt_(toolkit)) [widget toolkit](/source/widget_toolkit), can render images based on [.3ds](/source/.3ds) files. The stand-alone version of Freestyle is not under active development anymore, since 2008.

Freestyle is integrated with [Blender](/source/Blender_(software)) as of version 2.67.<ref>{{cite web|title=Blender 2.67: Freestyle Line Rendering Engine|url=http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.67/FreeStyle|accessdate=23 June 2013|date=May 2013|archive-url=https://web.archive.org/web/20130606091728/http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.67/FreeStyle|archive-date=6 June 2013|url-status=dead}}</ref> The Freestyle version integrated with Blender is under active development.<ref>{{cite web|title=Freestyle integration into Blender|url=http://freestyleintegration.wordpress.com/|accessdate=23 June 2013}}</ref>
