TU Wien Rendering #21 - Tone Mapping Basics
This lecture is held by Thomas Auzinger. In the first lecture, we discussed that we're trying to simulate light transport and measure radiance. That sounds indeed wonderful, but we can't display radiance on our display device, can we? We have to convert it to RGB somehow. It turns out that
