Abstract

U sklopu ovog rada objašnjen je algoritam praćenja zrake te koje su prednosti tog postupka iscrtavanja. Objašnjena je složenost ovog postupka te potrebne optimizacije i strukture podataka kako bi se ovaj algoritam mogao izvoditi u realnom vremenu i kako je to implementirano unutar platforme Nvidia RTX. Rad daje kratak uvod u grafičko programsko sučelje Vulkan te predstavlja različite koncepte i modele globalnog osvjetljenja koji se tipično koriste uz algoritam praćenja zrake. Algoritam je implementiran koristeći već spomenuto grafičko programsko sučelje Vulkan i Nvidia RTX platformu. Kao rezultat implementacije dani su primjeri refleksije, refrakcije i refleksije na grubim površinama te uspoređeni sa stvarnim ponašanjem svjetlosti.

Abstract (english)

This paper explores raytracing algorithm and why it is used. It is explained which optimisations and data structures are required for real time raytracing and how it is solved inside Nvidia RTX platform. It gives a brief introduction to modern graphics API Vulkan and introduces different concepts and global illumination models typically used by raytracers. The raytracer is implemented using already mentioned graphics API Vulkan and Nvidia RTX platform. As part of implementation, several examples of light reflections, refractions and rough surface reflections using described algorithms are presented and compared to real light behavior.
