An open source, physically-based global illumination rendering engine from a small team primarily designed for animation and visual effects.
Take a look at appleseed, an open source, physically-based global illumination rendering engine primarily designed for animation and visual effects. The tool is being developed by a small, international team of talented volunteers from the animation and VFX industry.

appleseed is said to implement a modern workflow based on path tracing that enables artifact-free, single pass rendering with very little technical tuning. The toolkit is simultaneously capable of strictly unbiased rendering when total accuracy matters, and biased rendering when artistic freedom and shorter rendering time are paramount.

The engine supports fully programmable shading via Sony Pictures Imageworks’ Open Shading Language (OSL), RGB/spectral/mixed rendering, fast and robust transformation and deformation motion blur, ray traced subsurface scattering, Python and C++ APIs and many other production-oriented features.
