Cycles – physically based production renderer

Cycles is an physically based production renderer developed by the Blender project. It is designed to provide physically based results out-of-the-box, with artistic control and flexible shading nodes for production needs.

The renderer provides unidirectional path tracing with multiple importance sampling, multi-core CPU rendering with SIMD acceleration, and GPU rendering with NVIDIA CUDA and OptiX & AMD OpenCL. There’s also multi-GPU support, and a unified rendering kernel for CPU and GPU.

This is free and open source software.
