Aim of 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.

Notes

Lecture slides

Student feedbacks for 2013 are available here.
 
Based on your feedbacks, I have added the following (Károly Zsolnai):
- Added the names in the LuxRender scene committee (Unit 05, slide ~236),
- Added some useful tips in the Blender Bonus unit (slide 12),
- I have updated smallpaint with a lot more comments to be more understandable.
 

Lots of new things are now added to the State-of-the-art lecture notes:
- PSSMLT rendering visualizations slides 133-134.,
- SPPM rendering visualization, slide 164,
- SPPM advantages/disadvantages, slides 171-173,
- Manifold Exploration MLT visualization, slide 216,
- PSSMLT and Manifold Exploration MLT side-by-side render comparison, slide 218.

These visualizations are lots of fun, and they are also worth a thousand words. Be sure to check them out!
