Synopsis:

We deal with techniques and algorithms for global illumination used in realistic rendering. The lectures partly complete the missing part of continuous mathematics required for this subject and numerical integration methods. The related physics underlying the rendering equation is shortly described which includes the surface reflectance. Most of the lectures are devoted to particular rendering algorithms for virtual and augmented reality. The use of GPUs for rendering algorithms is described in the last lectures.

Requirements:

The credits are given based on the individual or team project. The exam is based on the lectures.
