Manipulating Photorealistic Renderings | Two Minute Papers #9
Photorealistic rendering (also called global illumination) enables us to see how digital objects would look like in real life. It is an amazingly powerful tool in the hands of a professional artist, who can create breathtaking images or animations with. However, for the longest time, artists didn’t use it in the movie industry because it did not offer a great artistic freedom – after all, it works according to the laws of physics, which are exact. This piece of work enables us to apply artistic edits to photorealistic renderings easily and intuitively. I believe this one has the potential to single-handedly change the landscape of photorealistic rendering on a production scale.

I held a course on photorealistic rendering at the Technical University of Vienna. Here you can learn how the physics of light works and to write programs like this:
