Abstract

Napredak brzine obrade podataka na računalu direktno utječe na kvalitetu
računalne grafike koja se može ostvariti u interaktivnim aplikacijama. Mnogi
zanimljivi, ali kompleksni vizualni efekti se sve više mogu ostvariti unutar
zahtjeva interaktivnosti. Jedan od takvih efekata je kaustika. Učinak kaustike
nastaje kada se svjetlosne zrake zbog refrakcije ili refleksije fokusiraju na
manji dio površine. Cilj rada je usporedba različitih metoda ostvarivanja tog
vizualnog učinka na računalu u stvarnom vremenu. Opisana je implementacija
tehnike mapiranje kaustike u programskom jeziku C++ korištenjem biblioteke
OpenGL. Osim te implementacije, za demonstraciju i usporedbu korištena je i
tehnologija Nvidia OptiX za ostvarenje učinka kaustike tehnikom praćenja
zrake.

Abstract (english)

Advancement of computer data processing speed directly influences the
quality of computer graphics which can be realised for interactive
software. Many interesting, albeit complex visual effects can increasingly be
implemented within interactive constraints. One such effect is caustics. The
visual effect of caustics appears when light concentrates on a smaller part of
a surface due to reflection and refraction. The goal of this thesis is to
compare the different methods for rendering of this visual effect in real
time. This paper describes the implementation of caustic mapping technique
using C++ programming language and OpenGL library. Alongside the described
implementation and for purposes of comparison, the Nvidia OptiX technology was
used to demonstrate the rendering of caustics using ray tracing algorithm.
