This application is part of Master's thesis about arealights methods in real-time.
This project implements and compares three methods of implementing area lights:
- native point light cluster
- slow, but accurate Monte-Carlo method
- linearly transformed cosines with custom fitter which can be found in sienkiewiczkm/ltc_fitter repository
Thesis text (in Polish) can be found in sienkiewiczkm/arealights-thesis sienkiewiczkm/arealights-thesis repository.
