Abstract

U ovom radu je proučena fizikalna pozadina modela koji se koriste kod infracrvenih simulacija virtualnih scena. Opisani su radiometrijski zakoni, Kirchoffov zakon, Planckov zakon, zračenje crnog tijela, savršena zrcalna i difuzna reflaksija, prijenos zračenja kroz atmosferu, propusnost atmosfere i načini izmjene topline. Nakon toga je razmotrena bidirekcijska funkcija distribucije refleksije i njene komponente. Ova funkcija je vrlo bitan dio simulacija koje žele postići vjerodostojan prikaz refleksije svjetlosti i zračenja kroz scenu. Nakon fizikalnog modela, opisani su algoritmi iscrtavanja koji se koriste u računalnoj grafici pri simulacijama kretanja svjetlosti kroz scenu i alati korišteni u programskom rješenju. Također su razmatrani i već gotovi modeli, koji se koriste u svrhu simuliranja infracrvenih scena. Na kraju su razrađene mogućnosti poboljšanja implementiranog rješenja i iznesena su zaključna razmatranja predstavljene problematike.

Abstract (english)

This thesis studies the physical background of the models used in infrared simulations of virtual scenes. Radiometric laws, Kirchoff's law, Planck's law, black body radiation, perfect spectral and diffuse reflection, radiation transmission through the atmosphere, atmospheric permeability and ways of heat exchange are described. After that, bidirectional reflectance distribution function and its components are considered. This function is a very important part of simulations that want to achieve a credible display of light reflection and radiation. After the physical model, drawing algorithms used in computer graphics in simulations of light movement through the scene and tools used in the software solution are described. Prefabricated models which are used for the purpose of simulating infrared scenes are also considered. Finally, the possibilities of improving the implemented solution are elaborated and the concluding considerations of the presented problems are presented.
