LuxRender is a physically-based, unbiased renderer.
Based on state of the art algorithms, LuxRender simulates the flow of light according to physical equations, thus producing realistic images of photographic quality.
LuxRender is available for Mac OS, Linux, and Windows. It supports multi-core machines and network rendering using heterogenous nodes.
LuxRender is built on physically based equations that model the transportation of light. This allows it to accurately capture a wide range of phenomena which most other rendering programs are simply unable to reproduce. This also means that it fully supports high-dynamic range (HDR) rendering.
LuxRender features a variety of material types. Apart from generic materials such as matte and glossy, physically accurate representations of metal, glass, and car paint are present. Complex properties such as absorption, dispersive refraction and thin film coating are available.
LuxRender supports a wide variety of GPUs via the OpenCL interface. This means that rendering can be performed using both the CPU and the GPU, and multiple GPU, possibly from multiple vendors.
LuxRender is and will always be free software, both for private and commercial use. It is being developed by people with a passion for programming and for computer graphics who like sharing their work. We encourage you to download LuxRender and use it to express your artistic ideas. (learn more)
