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.

Shader Demonstration Using OpenSceneGraph and QT Libraries
Harman, Peter ; Bartoň, Radek (referee) ; Švub, Miroslav (advisor)
Assignment of this work is to zoom in the work with vertex and fragment processor for users. Programs for these processors are called vertex and fragment shaders. They may be written in a various programming languages intended for them (HLSL, Cg...), however in the work is going to be discussed OpenGL Shading Language (GLSL). There are going to be demonstrated this techniques of advanced rendering: Phong shading, Blinn-Phong shading Lambert illumination, Gouraud shading Later on is going to be described work with library OpenSceneGraph, as a library based on OpenGL and its integration with library for generating user's interface. The result is going to be a multiplatform application demonstrating connection between QT and OpenSpaceGraph libraries with integrated tutorial describing whole process of implementation. Theoretical background is going to be included as well.

Education Computer Program for Demonstration Methods of 3D Objects Illumination and Shading
Chvál, Vít ; Herout, Adam (referee) ; Zuzaňák, Jiří (advisor)
This work describes an Education Computer Program for Demonstration Methods of 3D Objects Illumination and Shading creation. There are in detail described lighting models in this text. There are Phong and Lambert models as representatives of empiric models and BRDF as representative of physical model. Next part of the text describes types of shading methods. You can find there constant, Gouraud and Phong method. Following part of the text discuss issues of Educational applications. The rest of the text is devoted to design and implementation of the application.
