LensSim is a C++ library and GUI tool for photographic lens system.
It's goal is to make C++ library for optical computations in lens design, and make user-friendly Python GUI tool to help lens design tasks.
LensSim can simulate image of photographic lens with Image Based Lighting(IBL) by Montecarlo Light Transportation.
Rendering of double gauss lens(data/dgauss50mm.json).
You can see some aberrations like chromatic aberration, and lens flare.
