Fast Ray-Scene Intersection
Stříž, Martin ; Zemčík, Pavel (referee) ; Herout, Adam (advisor)
Ray-tracing of 3-D scene is one of the contemporary used rendering methods. Altough it is not a photorealistic method, it produces results with high image quality. Main disadvantage of this method is that it needs a large amount of processing power. That is why various optimalizations must be implemented. This thesis is focused on spatial subdivision optimalizations, namely BSP and KD trees, and their comparsion.

Photon Tracing on GPU
Galacz, Roman ; Navrátil, Jan (referee) ; Polok, Lukáš (advisor)
Subject of this thesis is acceleration of the photon mapping method on a graphic card. The photon mapping is a method for computing almost realistic global illumination of the scene. The computation itself is relatively time-consuming, so the acceleration of it is a hot issue in the field of computer graphics. The photon mapping is described in detail from photon tracing to rendering of the scene. The thesis is then focused on spatial subdivision structures, especially to the uniform grid. The design and the implementation of the application computing the photon mapping on GPU, which is achieved by OpenGL and CUDA interoperability, is described in the next part of the thesis. Lastly, the application is tested properly. The achieved results are reviewed in the conclusion of the thesis.

Ray Tracing Using k-D Tree
Musil, Petr ; Jošth, Radovan (referee) ; Havel, Jiří (advisor)
This thesis describes the design and implementation of an application for picture synthesis using ray tracing. The goal is to verify properties of an space subdivision optimalization method using KD tree. The work compares spatial median, objects median and cost model methods for splitting plane determination during KD-tree construction. Several test scenes are used for evaluation.

Optimized Ray Tracing
Brich, Radek ; Herout, Adam (referee) ; Zemčík, Pavel (advisor)
Goal of this work is to write an optimized program for visualization of 3D scenes using ray tracing method. First, the theory of ray tracing together with particular techniques are presented. Next part focuses on different approaches to accelerate the algorithm. These are space partitioning structures, fast ray-triangle intersection technique and possibilities to parallelize the whole ray tracing method. A standalone chapter addresses the design and implementation of the ray tracing program.
