Fast Ray-Triangle Intersection
Havel, Jiří ; Zemčík, Pavel (referee) ; Herout, Adam (advisor)
Triangle is the mostly used primitive in computer graphics. Calculation of its intersection with a ray has many applications and is often a bottleneck of a program. This work focuses on its usage and various methods of calculation. It tries to combine these techniques to achieve high performance on modern processors.

Fast Computation of Ray-Triangle Intersection
Procházka, Václav ; Havel, Jiří (referee) ; Herout, Adam (advisor)
In this thesis we try to examine speed of 6 methods for ray-triangle intersection computation, which is elementary operation performed in raytracing. We examine their software implementations in C++ and SSE, for both single-ray and 4-ray packet implementation, as well as their hypothetical hardware implementation. Methods are tested with both randomly generated and real scenes and best results were measured for method Havel Herout (SSE4) among single-ray implementations and Shevtsov's method (SSE) among ray-packet implementations, where Shevtsov's method is of those two more suitable for hardware implementation.

Pathtracing on GPU
Březina, Karel ; Kobrtek, Jozef (referee) ; Polok, Lukáš (advisor)
This bachelor thesis focuses on the acceleration of rendering algorithm pathtracing. Thesis's goal is demonstration and performance comparison between implementation on CPU and GPU. Both implementations will be discussed and compared between themselves. Furthermore, will be describe possibilities of extending existing application.

Photorealistic Rendering Using "Photon Mapping" Method
Lysek, Tomáš ; Herout, Adam (referee) ; Zemčík, Pavel (advisor)
This master thesis focuses on photon mapping rendering technique. A simple photon mapping was implemented as a baseline and then progressive photon mapping was prepared for CPU and GPU. After implementing progressive photon mapping on GPU, further acceleration techniques were proposed. Finally, in the thesis, genetic clustering algorithm for suitable clusters on GPU was proposed.

Open Computing Language for .NET
Sakiqi, Fatjon ; Tichý, Vladimír (advisor) ; Pecinovský, Rudolf (referee)
This thesis concentrates on the Open Computing Language standard and the possibilities it offers to the .NET framework. By joining the advantages of these technologies one can obtain a solution, which is powerful and easy to use in many types of electronic devices, ranging from smart phones to dedicated computing servers. The practicality and efficiency of this project is verified on a series of raytracing tests, which are run using different PC components for comparison.
