Methods for Alias-Free Shadows Rendering
Posolda, Jan ; Polok, Lukáš (referee) ; Navrátil, Jan (advisor)
This paper concerns aliasing removal methods during the shadow displaying. Method of shadow mapping, its principles, procedure and mainly its drawbacks in the form of aliasing development are described. For the removal of this undesirable phenomenon, several aliasing suppressing methods are described - Percentage Closer Filter, Variance Shadow Map, Convulotion Shadow Map, Exponential Shadow Map a Bilateral Filter. I conclude my work with a proposal and implementation of a demonstrative application, which demonstrates the implemented results adequately. Also, the comparison of individual methods on the basis of their quality and computational demands is included.

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.
