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.

Pathtracing on GPU
Hájek, Ondřej ; Lysek, Tomáš (referee) ; Polok, Lukáš (advisor)
This bachelor thesis focuses on acceleration of global illumination method called Pathtracing. The goal of this thesis is a demonstration and performance comparison of different implementations of this method on GPU as well as CPU. Implementation will compose of two scenes. One simpler to verify correctnes of used algorithm and one more complicated to demonstrate various effects. The effectiveness and efficiency of said implementations will be analyzed and compared. Additionally, future program expansion and improvements will be discussed.

Streaming Ray Tracer on GPU
Dvořák, Jakub ; Jošth, Radovan (referee) ; Herout, Adam (advisor)
Current consumer GPUs can be used as high performance stream processors and are a tempting platform to be used to implement raytracing. In this paper I briefly present raytracing principles and methods used to accelerate it, modern GPUs programmable pipeline and examples of its use. I describe stream processing in general and available interfaces enabling the usage of GPU as stream processor. Then I present my GPU raytracer implementation, used algorithms and experiments I have made.

Scene Rendering in Modern Computer Games
Wilczák, Martin ; Šolony, Marek (referee) ; Kajan, Rudolf (advisor)
This thesis describes methods for lighting calculations of large scenes used in modern computer games. Forward shading and deferred shading methods are discussed and compared. Capabilities of raytracing are shortly described. There are some information about various methods for casting shadows, simulation of particle systems and applying post-processing effects. In the end there is a design of architecture for rendering complex scenes with use of XNA and description of implementation used in resulting game.

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.

Realistic Visualisation of Alcoholic Beverages
Bartl, Vojtěch ; Kučiš, Michal (referee) ; Polok, Lukáš (advisor)
The object of thesis was to make a simple program for visualisation of alcoholic beverages. There was used a global illumination method raytracing, which serve the purpose to visualize 3D scene in photorealistic quality. The rays sent to the scene reflects and refracts on the interfaces and getting information about color of materials. Finally the ray determine the color of pixel. It's a very complicated process where it is necessary to solve passing rays through different interfaces.

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.

Raytracing of Virtual Graphics Scenes
Rypák, Andrej ; Havel, Jiří (referee) ; Pečiva, Jan (advisor)
This thesis is dedicated to ray tracing based rendering methods, primarily the original ray tracing. Besides introducing a brief historical overview of algorithms from the family, it presents all the essential tools, techniques and physics needed for designing a rendering application in detail. A significant part of the document consists of an implementation of a photorealistic rendering application for interactive graphics 3D virtual scenes. The focus is on rendering without using any additional model information. The thesis includes descriptions and explanations of specific problems and their solutions.

Visualization of 3D data in biomedical applications
Karzel, Michal ; Harabiš, Vratislav (referee) ; Štohanzlová, Petra (advisor)
This thesis describes the basic principle of optical coherence tomography and prepro- cessing of the measured raw data. Preprocessing is focused mainly on noise filtration, removing artifacts, normalization, conversion and compression of raw data. In this way preprocessed data is saved in a *. PFRG file as ”preprocessed fringe data”. Those pre- processed data will be visualised by simply software, which support three methods of visualisation. Volume data represented by voxels. Reconstruction of volume by marching cube algorithm. Cuts through volume along X, Y and Z axis.
