Photorealistic Rendering
Lysek, Tomáš ; Kučiš, Michal (referee) ; Zemčík, Pavel (advisor)
The thesis describes implementation of photorealistic method. The first part describes the procedures and techniques, that are used to display photorealistic scenes such as raytracing, radiosity or photon mapping and other techniques used in computer graphics. The second part of thesis is focused on evaluation of current state of problem. In this part is also described reason of choosing this topic and thesis assignment is there more specified. The last part of thesis is focused on implementation details of photorealistic method.

Photon Mapping
Nečas, Ondřej ; Španěl, Michal (referee) ; Herout, Adam (advisor)
This thesis deals with practical implementation of photon mapping algorithm. To achieve better results some basic and some more advanced methods of global illumination has been examined. These time demanding algorithms are often practically unusable and their further optimization is necessary. Optimized ray tracer is essential for practical implementation. Computing diffuse interreflection by Monte Carlo sampling is also very time demanding operation. Therefore it is appropriate to use it along with proper interpolation.

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.

Photorealistic Rendering
Melcer, Pavel ; Lysek, Tomáš (referee) ; Zemčík, Pavel (advisor)
This bachelor thesis deals with the realistic rendering of 3D scenes, which describes the procedures leading to the photorealistic image. First are mentioned ways to definition objects, how the scene is rendered on screen, the types of light source and surface characteristics of materials. The work is also a description of the local shading model, optical phenomena and the methods used to realistically display (raytraycing, pathtraycing, radiosity and photon mapping). Next part mentions the reason for choosing the topic and description of implementation methods raytraycing and photon mapping.

Physically-based Cloud Rendering on GPU
Elek, Oskár ; Wilkie, Alexander (advisor) ; Křivánek, Jaroslav (referee)
The rendering of participating media is an interesting and important problem without a simple solution. Yet even among the wide variety of participating media the clouds stand out as an especially difficult case, because of their properties that make their simulation even harder. The work presented in this thesis attempts to provide a solution to this problem, and moreover, to make the proposed method to work in interactive rendering speeds. The main design criteria in designing this method were its physical plausibility and maximal utilization of specific cloud properties which would help to balance the complex nature of clouds. As a result the proposed method builds on the well known photon mapping algorithm, but modifies it in several ways to obtain interactive and temporarily coherent results. This is further helped by designing the method in such a way which allows its implementation on contemporary GPUs, taking advantage of their massively parallel sheer computational power. We implement a prototype of the method in an application that renders a single realistic cloud in interactive framerates, and discuss possible extensions of the proposed technique that would allow its use in various practical industrial applications.

Optimal strategy for connecting light paths in bidirectional methods for global ilumination computation
Vorba, Jiří ; Křivánek, Jaroslav (advisor) ; Wilkie, Alexander (referee)
This work introduces a method for optimal combination of light paths generated from the camera and from the light sources in the Photon Mapping algorithm used for computing global illumination. Our method is based on Multiple Importance Sampling, a general approach, introduced by Veach, for adaptive path connection in Bidirectional Path-Tracing. Our goal is to examine this method in connection with the biased algorithm of Photon Mapping and to improve the ineffective heuristic used in the original version of this algorithm. This heuristic is usually problematic when applied to the scenes where highly glossy materials prevail.
