Kerkythea
What it is
Kerkythea is a free staging application for rendering 3D models with physically accurate materials and lights. Its scene setup interface includes a GL real-time viewer, material editor, and general and render settings. The material editor provides control over final material appearance, while path tracing supports rendering and the software also supports animation rendering. Kerkythea accepts .3ds and .obj models, and the site provides a free SketchUp exporter and SketchUp plugin. Resources include material libraries, skies, material scenes, and models. Documentation offers PDF tutorials covering setup, global-illumination interior lighting, walkthrough animation, render presets, and material editing. The software runs on Windows, Linux, and macOS. Download links require completing a form. The forum is read-only with registrations disabled. The site footer attributes copyright to Altair Engineering, Inc.
