This rendering course is an MSc-level class at the Technical University of Vienna. It is about ray tracing, photorealistic rendering and global illumination. The lecture was usually held for 20-30 students at a time, which makes it one of the more popular courses in the Master’s curriculum. However, I believe that the teachings should be for everyone and not be a privilege of only a few. So here you go, the whole rendering course is now available online!

Aim of the course
This course aims to give an overview of basic and state-of-the-art methods of rendering. Offline methods such as ray and path tracing, photon mapping and many other algorithms are introduced and various refinement are explained.
The basics of the involved physics, such as geometric optics, surface and media interaction with light and camera models are outlined.
The apparatus of Monte Carlo methods is introduced which is heavily used in several algorithms and its refinement in the form of stratified sampling and the Metropolis-Hastings method is explained.
At the end of the course students should be familiar with common techniques in rendering and find their way around the current state-of-the-art of the field. Furthermore the exercises should deepen the attendees’ understanding of the basic principles of light transport and enable them to write a simple rendering program themselves.
