Mitsuba 2 is a research-oriented retargetable rendering system, written in portable C++17 on top of the Enoki library.
It is developed by the Realistic Graphics Lab at EPFL.
It can be compiled into many variants which include color handling (RGB, spectral, monochrome), vectorization (scalar, SIMD, CUDA) and differentiable rendering.
Mitsuba 2 consists of a small set of core libraries and a wide variety of plugins that implement functionality ranging from materials and light sources to complete rendering algorithms. It strives to retain scene compatibility with its predecessor Mitsuba 0.6.
