LuxRender is a new, open-source, free software rendering system for physically correct, unbiased image synthesis.

Rendering with LuxRender means simulating the flow of light according to physical equations. This produces realistic, photographic-quality images.

It's an authorized fork of the PBRT project, focusing on production rendering and artistic efficiency.

Please read our Features and Goals and philosophy pages for more information.

Why another unbiased renderer? Read our FAQs page for details.

LuxRender comprises an interactive GUI, a command line tool and Blender exporter plugins.
For developers we also provide a C/C++ API that allows embedding LuxRender into third-party applications.

LuxRender runs on GNU/Linux, MS-Windows(R) and MacOS X(R) platforms.
