Datové struktury počítačové grafiky
Obsahem předmětu je seznámení se s datovými strukturami používanými v grafických algoritmech. Důraz je kladen na základní a hierarchické datové struktury nad bodovými a objektovými daty, z hlediska aplikací datove struktury pro vyhledávání nejbližšího souseda, metodu sledování paprsku, z-buffer a detekci…

Realistická syntéza obrazu
Předmět se zabývá technikami a algoritmy globálního osvětlení používanými pro vytváření realistických obrazů na počítači (realistický rendering). Několik přednášek se věnuje matematickým a fyzikálním základům výpočtu globálního osvětlení: popis rozložení světla ve scéně, odraz světla na površích objektů,…
