Hybrid Raytracing in DXR
Polášek, Tomáš ; Matýšek, Michal (referee) ; Kobrtek, Jozef (advisor)
The goal of this thesis is to evaluate the usability of hardware accelerated ray tracing in near-future rendering engines. Specifically, DirectX Ray Tracing API and Nvidia Turing architecture are being examined. Design and implementation of a hybrid rendering engine with support for hardware accelerated ray tracing is included and used in implementation of frequently used graphical effects -- hard and soft shadows, reflections, and Ambient Occlusion. The assessment is made in terms of difficulty of integration into a rendering engine, performance of the resulting system and suitability of implementation of chosen graphical effects. Performance parameters -- including number of rays cast per second, time to build acceleration structures and computation time on the GPU -- are tested and discussed.

Generation of Infographics for Live Streaming
Krejčík, Marek ; Starka, Tomáš (referee) ; Matýšek, Michal (advisor)
Main goal of the work was to create application for static and dynamic graphic creation for use in electronic sports live broadcast. Program should be able to create static graphics for individual matches and also generate dynamic graphics based on responses obtained from Riot Games' servers during a live game. It should also be able to send the acquired graphics to the editing device without using keying.

Advanced Character Animation
Matýšek, Michal ; Polok, Lukáš (referee) ; Kajan, Rudolf (advisor)
This thesis describes modern real-time character animation techniques and their implementation in C++ language using DirectX and PhysX libraries. The first part of the text deals with a presentation of selected animation principles and is focused mailny on key-frame animation, skeletal animation, morphing and ragdoll simulation. Then follows a description of used DirectX and PhysX libraries and description of motion capturing, using iPi Desktop Motion Capture software. The second part of this thesis is focused on particular ways of implementation of the described animation techniques.

Training Intelligent Agents in Unity Game Engine
Vaculík, Jan ; Chlubna, Tomáš (referee) ; Matýšek, Michal (advisor)
The goal of this work is to design applications, which demonstrate the power of machine learning in video games. To achieve this goal, this work uses the ML-Agents toolkit, which allows the creation of intelligent agents in the Unity Game Engine. Furthermore, a series of experiments showing the properties and flexibility of intelligent agents in several real-time scenarios is presented. To train the agents, the toolkit uses reinforcement learning and imitation learning algorithms.

Terrain Generation and Adjustement
Oplatek, Tomáš ; Matýšek, Michal (referee) ; Starka, Tomáš (advisor)
The goal of this thesis was to create an application, which allows the end user to generate any area on earth as a 3D map, which they could look at and get to know, before they set out on a journey there. The application was developed as a desktop application in the C++ language with the use of OpenGL to render the result and Qt framework for user interface. Added value of this application is, that it allows to set for example the density of vegetation, so that small paths, that are usually hidden are visible and it provides real paths even in lesser known areas.

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.

4K Video Player for Virtual Reality
Chvíla, Václav ; Matýšek, Michal (referee) ; Kobrtek, Jozef (advisor)
The subject of this work is the implementation of 4K video player for virtual reality. Theoretical part describes the origin of 360° videos, their compressions and rendering. In design of application was choosed solution with OpenGL, OpenVR, Qt libraries and commercial codec jpeg2000 developed by Comprimato company and for virtual reality device the HTC Vive headset. In part of implementation is analysed problem of shared video memory between libraries and discusses optimalization of the video player. Application was tested in perfomance and by users.

Graphics Intro 64kB Using OpenGL
Menšík, Jakub ; Milet, Tomáš (referee) ; Matýšek, Michal (advisor)
This Bachelor's thesis deals with the creation of a graphics intro with the executable file size limited to 64kB. The graphics intro is created using the OpenGL API and related libraries. The thesis describes many techniques for a graphics content generation including procedural generation, Perlin noise, mipmaps, volumetric light, face culling, instancing, fog, skybox, and techniques used for reduction of a size of the executable files. The result is a graphical intro showing a night city.

Graphics Demo Employing Procedural Textures
Drevický, Dušan ; Matýšek, Michal (referee) ; Polok, Lukáš (advisor)
This thesis deals with the design and implementation of a size-limited 64 kB graphics demo. Procedural generation is used for the definition of structure and appearance of realistic natural terrain. The terrain is described by a heightmap based on noise functions described in this work. Rendering utilizes the ray marching method and is done in real time. All parts of the implementation described in this work were created exclusively within the fragment shader of the GPU.
