Advanced course of computer graphics focused on 3D graphics and realistic rendering. Main topics: lighting models, smooth shading,
ray tracing including acceleration techniques, anti-aliasing, distributed ray tracing, sampling methods, textures, Monte-Carlo methods, radiosity methods: hierarchical radiosity, adaptive mesh
subdivision.
Labs: modules for JaGrLib library in Java language.
Continuity: Computer Graphics III (PGR010).

Student must have enough lab assignments finished (at least handed in) before going to an exam.
Lab credit requirements are explained in detail on the page: http://cgg.mff.cuni.cz/~pepca/lectures/cv/npgr004.en.php The same URL explains the grading system of the subject.
Exam can be repeated. Lab credit repetition is irrelevant. Last update: Pelikán Josef, RNDr. (22.06.2018)

Exam is written and oral (basis is written, there is a possibility to call a student for short discussion over the answers).
Every topics presented at lectures can be examined (exceptions are mentioned specifically): http://cgg.mff.cuni.cz/~pepca/lectures/npgr004.current.en.php http://cgg.mff.cuni.cz/~pepca/lectures/npgr004.slides.en.php
Overall grading is based on lab credit (50-80 points) + exam points (0-100 points). Grading table - together with further details - can be found on http://cgg.mff.cuni.cz/~pepca/lectures/cv/npgr004.en.php
