Full photon mapper: https://scratch.mit.edu/projects/863739356/ Use it here for faster results: https://turbowarp.org/861098355/fullscreen?turbo For the number of photons, I recommend an input of 40000 to 750000. For the photon lifetime I recommend an input of -0.3 to -0.8. All code by me, @18-7. This is a demonstration so there are no actual calculations or light bounces.
