Abstract
U pokušaju poboljšanja realizma u računalnoj grafici koristi se čitav niz modela osvjetljenja s različitim prednostima i manama. Rad pregledava nekoliko metoda globalnog osvjetljenja te predlaže metodu koja aproksimira osvjetljenje u stvarnom vremenu koristeći izmijenjeno oktalno stablo. Opisuje metode simulacije propagacije, generacije potrebnih podataka i prikaza izračunatog osvjetljenja. Nakon opisa modela opisana je primjena u pogonskom sustavu za iscrtavanje Ogre3D, kao i prednosti i poteškoće rada u tom sustavu. Prikazuje i komentira vizualne rezultate metode na nekoliko scena te uspoređuje cijenu algoritma na prikazanim scenama. Promatrajući rezultate daje zaključak o potrebama daljnjeg razvoja algoritma te predlaže nekoliko metoda unaprjeđenja performansi i kvalitete prikaza te rješavanja pronađenih poteškoća i rubnih slučajeva algoritma.
Abstract (english)
In an attempt to improve the realism of computer graphics many models of illumination are used, each with its own advantages and disadvantages. This paper outlines several methods of global illumination and introduces a method that aproximates global illumination in realtime using a modified octree-like structure. It describes methods of light propagation simulation, generation of needed data and rendering of calculated lighting. After presenting the model, an implementation is described using the Ogre3D rendering engine, along with advantages and issues of working with that engine. Visual results in several scenes are shown and commented, after which performance costs are compared in those scenes. By analysing the results a conclusion is given on requirements of further development and finally, several methods of performance and visual quality improvement are discussed along with potential solutions of issues and edge cases.
