Kerkythea is a freeware rendering system that supports raytracing. Currently, it can be integrated with 3ds Max, Blender, SketchUp, Silo and Wings3D (typically any software that can export files in obj and 3ds formats). Kerkythea is a standalone renderer, using physically accurate materials and lighting.

History

Kerkythea started development in 2004 and released its first version on April 2005. Initially it was only compatible with Microsoft Windows, but an updated release on October 2005 made it Linux compatible
