The goal of the course is to deepen the students' knowledge in the area of computer graphics. After passing the course, the student will understand the basic principles of photorealistic rendering. He/she will be able to implement selected methods.

Lectures

Tutorials

The subject follows the introductory course Computer Graphics Basics and covers the basics of photorealistic image synthesis. In particular, following topics are discussed: ray tracking, illumination models, BRDF, rendering equation, fundamentals of the Monte Carlo method to simulate light transport, accelerate calculation, smoothing images. The subject includes exercises during which the topics discussed during lectures are practically realized in the form of implementation of programs for credits.
