Photon Splatting Using a View-Sample Cluster Hierarchy
Kiss, Marcel ; Starka, Tomáš (referee) ; Milet, Tomáš (advisor)
This thesis deals with the techniques of global illumination of the scene. The theoretical part discusses various techniques, focusing on processing in real-time using various optimization methods. It focuses to the technology of photon splatting using view sample cluster hierarchy. The main part is analysis, implenetation and measurement of mentioned method.

Volumetric Clouds
Barvíř, Marek ; Matýšek, Michal (referee) ; Starka, Tomáš (advisor)
This master thesis deals with creation of library for volumetric clouds. The paper describes specific techniques for creation and rendering volumetric clouds as clouds and atmospheric scattering. For rendering this type of effects we have to cover theory for participating media.

Shadow Rendering Using View Frustum Splitting Methods in OpenGL
Roháček, Dominik ; Starka, Tomáš (referee) ; Kobrtek, Jozef (advisor)
The content of this thesis discusses the generation of cascaded shadow maps in 3D applications. It describes two chosen methods of view frustum splitting into sub-frustum and discusses their differences. It was developed an application for analysation purposes in OpenGL which shows their advantages and disadvantages on three testing scenes. This work is focused on a comparison of drawing each split separately and using layered rendering. Data analysis proved some advantages of layered rendering. The PSSM was faster in accord to data analysis, but SDSM, on the other hand, produces more accurate shadows.

Procedural Generation of Cities
Bílý, Kristián ; Kobrtek, Jozef (referee) ; Starka, Tomáš (advisor)
Bachelor thesis is about procedural city generation. It's goal is to design, implement and test application, that is capable of city generation in user's terrain. The work uses L-Systems for generating road network. It also focuses on variation of building models. Final application is capable of city generation. Application properly reacts to user's input. User's input is basic city structure and terrain.

Rendering Using Deep Shadowmaps
Rejent, Tomáš ; Starka, Tomáš (referee) ; Polok, Lukáš (advisor)
Rendering shadows of transparent objects in real-time applications is difficult. The number of usable methods is limited by the available computing power. Depth Peeling and Dual Depth Peeling methods are described in this document. These allow rendering of transparent objects without the need of sorting them. Deep Shadow Maps are described as a method for rendering shadows of transparent objects. These methods were used to create an demonstration application. This application provides rendering of transparent objects and their shadows, including colored ones. The Application is build upon OpenGL and Qt framework. Evaluation of rendering speed according to various parameters is also part of this work.

LOD for GPUEngine
Staněk, Jan ; Milet, Tomáš (referee) ; Starka, Tomáš (advisor)
The representation of 3D polygonal model on several levels of available detail is a problem inherent in the process of rendering a scene. Highly-detailed models, if placed far from the camera, suffer from spatial aliasing that results from inadequate sampling of their surface, and require disproportionately large amount of time to render. Low-detailed models on the other hand reduce the visual quality of the scene when placed too near to the camera. This report delves in both the theory and the practical techniques used for solving these problems. It describes various published solutions and the principles behind them, and presents a design and an implementation of selected techniques for the GPUEngine library.

Rendering of Shadows in Graphics Scenes Using Shadow Volumes
Starka, Tomáš ; Herout, Adam (referee) ; Pečiva, Jan (advisor)
This work concerns itself with choosen methods of shadows in computer graphics. In short it discuses both shadow maps and shadow volumes, with their advantages and disadvantages. Then it employs itself on shadow volumes and their implementation utilizing Open Scene Graph toolkit. It deals with z-pass and z-fail methods and some possible optimizations. Moreover, it contains measuring of FPS and comparison of fill consumption of the scene and shadow volumes on various scenes.

Simple Game Engine
Štefáček, Michal ; Vlnas, Michal (referee) ; Starka, Tomáš (advisor)
Použití herního enginu značně urychluje proces vývoje her. Za posledních několik desetiletí vzniklo množství zdarma použitelných herních enginů, z nichž některé mají volně dostupný zdrojový kód. Cílem této práce je pochopení procesu vývoje takovéhoto softwaru. Pro zúžení rozsahu se projekt primárně zaměřuje na vývoj 2D her.

Raytracing for GPUEngine
Novák, David ; Milet, Tomáš (referee) ; Starka, Tomáš (advisor)
The main goal of this thesis is ray tracing optimization, especially with the use of acceleration data structure. It'll be focused on discretion about various structure build strategies and their traversal. Different algorithms on the CPU and on the GPU will be implemented and compared in the thesis, specifically will be compared the speed of build and final structure quality, which have a direct influence on ray tracing performance. A ray tracing application will be implemented for the purpose of the acceleration structure quality test. A part with acceleration structure building will be added to GPUEngine library.
