Realistic Visualisation of Alcoholic Beverages Using Distributed Raytracing
Fabík, Jiří ; Maršík, Lukáš (referee) ; Polok, Lukáš (advisor)
This work is about a realistic visualization technique called raytracing. It studies its original form, its extensions and optimizations. Raytracing casts rays through pixels and follows their propagation in the scene, according to the physical laws. It enables rendering of correct shadows, reflections and refractions. Distributed raytracing serves for better visualization and advanced effects. One ray is replaced with a beam of rays that allows soft shadows, fuzzy translucency, depth of field and antialiasing. With the increasing number of rays, the render time rises as well, so it is needed to use some optimization techniques and tools. A way of using this rendering method for visualization of alcoholic beverages is also described.

Distributed Ray Tracing in Reasonable Time
Slovák, Radek ; Polok, Lukáš (referee) ; Herout, Adam (advisor)
This thesis deals with the method of distributed ray tracing focusing on optimalization of this method. The method uses simulation of some attributes of light by distributing rays of lights and it produces high quality and partly realistic images. The price for realitic effects is the high computational complexity of the method. The thesis analysis the theory connected with these aspects. A large part describes optimalizations of this method, i.e. searching for the nearest triangle intersection using kd-trees, quasi random sampling with faster convergence, the use of SSE instruction set and fast ray - triangle intersection. These optimalizations brought a noticable speed - up. The thesis includes description of implementation of these techniques. The implementation itself emphasises the practical usability including generating some advanced animations and universal description of objects.

Distributed Ray Tracing
Slovák, Radek ; Jošth, Radovan (referee) ; Herout, Adam (advisor)
This project describes method for global display of distributed ray tracing. The method generates high quality and realistic two-dimensional images from mathematical specification of scene. The methods for solution of this issue are presented and analyzed. Integral part of this method - conventional ray tracing - is also presented.

Rendering Chess Using Ray Tracing
Vaverka, Martin ; Jošth, Radovan (referee) ; Herout, Adam (advisor)
This work aims at rendering 3D scene using ray tracing. It describes advantages and disadvantages of this technology and its alternation known as distributed ray tracing. Other part deals with method from different branch, which are closely related to distributed ray tracing - constructive solid geometry and procedural texturing.
