Abstract
Zadnjih par godina, kako je rasla snaga grafičkih kartica, dolazi i pitanje može li se koristiti neki bolji načini za prikaz korektnog osvijetljenja kod prikaza 3D objekata u računalnoj sceni. Tu stupaju na snagu algoritmi globalnog osvijetljenja, konkretno koji rade na principu praćenja zrake. Zrake se "ispucavaju" u scenu iz svakog piksela i vrati se boja koju taj piksel poprimi. Ti algoritmi su poznati još od 80tih, ali mana im je što zahtjevaju jako puno procesorskog vremena, pa su godinama ostali u sjeni. U zadnjih par godina, na karticama je uz malo truda moguća njihova implementacija, pa time ne moramo više koristiti procesor jer jednostvno možemo zaposliti male, brze, efikasne jezgre u grafičkoj jedinici da paralelno računaju boje tih zraka. U ovom radu smo istražili koji su to točno algoritmi, analizirali ih te dali implemtacije, na grafičkoj kartici i na CPU, kroz par različitih okolina, te smo istražiti njihove mane i kompleksnosti, i prikazali rezulate renderiranja.
Abstract (english)
In the last couple of years, as the power of graphic cards continued to grow, a primary question we should ask is, is there a better way to render correct lightning in 3D computer models? Global illumination algorithms, specifically ray tracing ones, show promise. Rays are shot toward the scene from each pixel, and they return a color that that pixel should be. These algorithms are known since the 80s, but their biggest flaw is their huge computing time, so they stayed in shadow for years. In the last couple of years, it became possible to use graphics cards for that purpose, where we can implement them, with some effort. So now we no longer need to use CPU, but instead use these small fast efficient GPU cores to compute our ray colors, all in parallel. In this thesis, we explored some of these algorithms, analyzed and gave implementations of them on GPU and on CPU through a couple of different environments, and then explored flaws of these algorithms and complexities. Finally, we showed final renders for each implementation.
