Large-Scale Rendering Using Shadowmaps
Spišiak, Ján ; Zemčík, Pavel (referee) ; Polok, Lukáš (advisor)
Shadow mapping is the most widely used method in real-time 3D graphics for producing shadows in local light models. This thesis step-by-step explains the process of creating shadow maps. Depth biasing as well as filtering methods are analysed, then the calculation of normal offset bias for variable sized kernels is derived. We describe the process of efficiently fitting stable cascade frustums to view frustum. Also shown is how to use modern OpenGL to reduce performance overhead.

Shadow Mapping: Shadow Filtering in OpenGL
Brída, Ján ; Polok, Lukáš (referee) ; Kobrtek, Jozef (advisor)
The content of this bachelor thesis discusses generation, and filtration ways of shadows in 3D applications. It describes possibilities to surpress the discretization phenomenon using certain techniques, and documents the artifacts typical for them. The reader will also learn about their performance, and quality differences, thereby being able to judge offered implementations.

Shadow Mapping: Shadow Filtering in OpenGL
Maresz, Šimon ; Polok, Lukáš (referee) ; Kobrtek, Jozef (advisor)
This thesis deals with filtration of shadow rendering in 3D scene with a focus on quality of rendered shadows. As part of this work was to create a sample application that implements the chosen algorithms that modifies the Shadow Mapping algorithm to render softer and more realistic shadows. The program was created in the integrated development environment Microsoft Visual Studio 2010 in C++. At the beginning the algorithms are explained for rendering of shadows. The conclusion is then engaged in testing and comparing of achieved results.
