In their own words
Mitsuba 3
Mitsuba 3 is a free, open-source, research-oriented system for forward and inverse light-transport simulation. It offers monochrome, RGB, and spectral rendering with optional polarization tracking, and computes derivatives with respect to camera pose, geometry, materials, textures, and volumes. Dr.Jit compiles rendering code for CPUs through LLVM and NVIDIA GPUs through CUDA and OptiX. Python integration supports development of materials, textures, and rendering algorithms, with documentation covering PyTorch interoperability. Installation is recommended through pip and requires Python 3.10 or later. Optional GPU computation requires NVIDIA driver 535 or later; parallel CPU computation optionally requires LLVM 18 or later. The project reports Linux x86_64, macOS aarch64 and x86_64, and Windows x86_64 support. Its plugins cover materials, light sources, and complete rendering algorithms. The Python package includes thirteen variants by default; more require compiling a custom Dr.Jit version with CMake. Tutorials, notebooks, how-to guides, and API and plugin references are provided.
RenderMan
RenderMan is Pixar’s production rendering software for visual effects and animation, available for Linux, macOS, and Windows. Its physically based tools include multi-bounce ray-traced global illumination and ray-traced subsurface scattering. RenderMan 27 adds XPU, a hybrid CPU/GPU renderer with multi-GPU support, and a machine-learning denoiser developed with Disney Research and trained on Disney and Pixar data. The Stylized Looks toolset supports approaches such as illustration and anime. Bridge tools connect it with Maya, Houdini, Solaris, Katana, and Blender, while supported standards include Alembic, OpenColorIO, OpenEXR, OpenVDB, OSL, and USD.
RenderMan requires an AVX-capable processor. XPU and the OptiX denoiser also need an Nvidia Pascal-or-newer GPU; XPU requires at least 12 GB of VRAM. Non-commercial use is free but limited to the latest version and excludes Stylized Looks. Commercial licenses are $595 per licence once; maintenance is $250 a year.
