How do we display the impossible brightness of light on a screen?
In short: Digital displays cannot replicate the true radiance of light. This lecture explores tone mapping, the essential process of converting complex light transport data into viewable RGB colors.
Presented by Thomas Auzinger, this lecture from the 2015 TU Wien course addresses the non-trivial challenge of mapping physical radiance to displayable values. The session provides an overview of rendering methods, ranging from offline algorithms like ray tracing and photon mapping to the physics of geometric optics and camera models.
The course also covers the Monte Carlo methods used to simulate light, including refinements such as the Metropolis-Hastings method and stratified sampling, providing the foundation for understanding modern rendering state-of-the-art.
