Path Tracing on GPU
Novák, David ; Milet, Tomáš (referee) ; Tóth, Michal (advisor)
The aim of this bachelor's thesis is an implemetation and following acceleration of Path Tracing algorithm. This algorithm will be implemented on the GPU using OpenGL. Above rendered scene will be built Octree data structure. Then the acceleration, which was achieved using this data structure, will be measured.

Graphics Intro 64kB Using OpenGL
Marek, Jan ; Tóth, Michal (referee) ; Milet, Tomáš (advisor)
This bachelor's thesis deals with the creation of a graphics intro with a limited size. It deals with methods used for its creation. The thesis describes methods used for reduction of size of executable files. Among them for example the use of prcedural generation and the use of exe packers. The created graphics intro has a size smaller than 64 kB.

3D Game World in OpenGL
Buchta, David ; Lysek, Tomáš (referee) ; Milet, Tomáš (advisor)
Focus of this master's thesis is a study of modern techniques in computer graphics and designing and developing custom application based on which could be developed new game engine. In this thesis are highlighted techniques for creating large terrains, advanced shadows, physically based sky rendering and drawing large set of objects. Finally, performance testing of these modules is performed.

Rendering of Nonplanar Mirros
Číž, Miloslav ; Pečiva, Jan (referee) ; Milet, Tomáš (advisor)
This work deals with the problem of accurately rendering mirror reflections on curved surfaces in real-time. While planar mirrors do not pose a problem in this area, non-planar surfaces are nowadays rendered mostly using environment mapping, which is a method of approximating the reflections well enough for the human eye. However, this approach may not be suitable for applications such as CAD systems. Accurate mirror reflections can be rendered with ray tracing methods, but not in real-time and therefore without offering interactivity. This work examines existing approaches to the problem and proposes a new algorithm for computing accurate mirror reflections in real-time using accelerated searching for intersections with depth profile stored in cubemap textures. This algorithm has been implemented using OpenGL and tested on different platforms.

Creation and Demonstration of Assets for VR Application
Zouhar, Marek ; Tóth, Michal (referee) ; Milet, Tomáš (advisor)
This thesis deals with the concept of virtual reality, its history, present-day possibilities and available devices and technologies for virtual reality and ways of creating assets such as models, textures and animations for virtual reality applications. The practical part of this work deals with design and creation of three-dimensional models, textures, animations and environment for use in interactive application in virtual reality and also with design and creation of such application to demonstrate their use.

VR Interactive Application
Novotný, Miroslav ; Tóth, Michal (referee) ; Milet, Tomáš (advisor)
The goal of this thesis is to learn about virtual reality and the aspects of the development for this platform. The next goal is to find well suited development environment for the application and test the capabilities and limits of them both. The thesis will be completed by designing, implementing and then testing the aplication using knowledge learnt.

3D Model Voxelization Using GPU for Further Processing
Brída, Ján ; Milet, Tomáš (referee) ; Španěl, Michal (advisor)
This thesis focuses on the analysis of the latest techniques for surface and solid binary voxelization of 3D models. It briefly describes current trends in this problematics and identifies a suitable method with an aim to parallelize the given solution on GPUs. It concretely explains the implementation process of the selected algorithm described in the paper Fast Parallel Surface and Solid Voxelization on GPUs , which produces a sparse voxel octree. The results are very close to those of the original authors. A new solution for extracting a smooth isosurface from this structure based on Marching Cubes is presented as well, providing up to 98 % reduction of the traversed cubes in higher resolutions. The resulting implementation is a framework usable for further voxel scene processing.

3D Racing Game
Vlach, Jan ; Milet, Tomáš (referee) ; Tóth, Michal (advisor)
This bachelor thesis focuses on desing and implementation of 3D racing game with graphical effects. The goal of this thesis is to create a racing game with the help of particle emitors. For collision detection is used Bullet physics library. Because of it, all players react to other scene objects. Terrain is generated from height map and supports multitexturing technique, which allows for multiple textures to be applied to terrain's surface. Game's racing track is defined by collision map. In thesis, there is an emphasis on creating editor for easy map creation and editation. Editor allows for drawing Kochanek-Bartels splines, which are then used to determine the movement of the oponents.

Real-Time Rendering of a Scene With Many Pedestrians
Pfudl, Václav ; Milet, Tomáš (referee) ; Herout, Adam (advisor)
The aim of this thesis was to implement a software that would be able to render, simulate and record a scene with walking pedestrians in real-time, with emphasis on rendering level of realism. The output of the application could serve as an input test data for people counting systems or similar systems for video recognition. The problem was divided into three major subproblems: character animation, artificial intelligence for character movement and advanced rendering techniques. The character animation problem is solved by the skeletal animation of the model. To achieve the characters moving in a scene autonomously path finding(A* algorithm) and group behaviors(steering behaviors) were implemented. Realism in a scene is added by implemented methods such as normal-mapping, variance shadow-mapping, deffered rendering, skydome, lens flare effect and screen space ambient occlusion. Optimaliaztion of the rendering was implemented using octree data structure for space partitioning. Rendering stage of a scene can be easily parametrized through implemented GUI. Implemented application provides the user with easy way of setting a scene with walking pedestrians, setting its visualization and to record the result.
