Synopsis:

This course builds on the APG course and focuses on the physical principles, description, and algorithms governing the propagation of light in a scene, with the aim of calculating the image using these algorithms in ANSI C++ language.

Requirements:

A prerequisite is successful completion of the APG course and a basic knowledge of ANSI C++.

Syllabus of lectures:

1. Introduction to the course, physical models of light propagation

2. Maxwells equations

3. Reflection and refraction of light at interfaces

4. Light measurement and light source models

5. Light detectors, the eye, and the camera

6. Reflectance measurement (BRDF, BTF, BSSRDF)

7. Mathematical modeling of reflectancedata and algorithms

8. Verification of rendering methods

9. Motion blur, depth of field, efficient computations

10. Important side methods of image computation

11. Selected rendering algorithms

12. Selected rendering algorithms continued

13. Non-photorealistic image calculation methods

Study Objective:

Students will acquire theoretical knowledge through lectures and practical knowledge through seminars, during which they will complete several small-scale assignments. Students will earn grades based on their performance on these seminar assignments. The scope of knowledge required for the final exam is determined by the content of the lectures and seminars.
