TU Wien Rendering, 2 Radiometry Recap, Light Attenuation

Before trying to understand the nature of light, we have to have a grip on the basic units our simulation can rely on. What quantity would be adequate for this Radiant flux Irradiance Radiance And what do these words mean, anyway We also briefly discuss how light is attenuated, why it s so hot at noon and why it s getting golder in the afternoon. About the course: This course aims to give an overview of basic and stateoftheart methods of rendering. Offline methods such as ray and path tracing, pho
