Particle Systems
Bedecs, Jakub ; Maršík, Lukáš (referee) ; Kajan, Rudolf (advisor)
This bachelor's thesis deals with the implementation of particle systems with the usage of calculation power of GPU. The purpose of this work is to describe all important facts about the particle systems construction and to show up various possibilities of its usage. It analysis the abilities of modern shaders and their usage for calculation of particles movement. The basis of this work is the analysis of the implemented application, which is able to dynamically change all parameters of the system.

Rendering Performance Comparison in iOS and Metal
Pištělák, Radek ; Milet, Tomáš (referee) ; Tóth, Michal (advisor)
The goal of this thesis is the comparison of the OpenGL ES and Metal graphical libraries on the iOS platform. To compare the performance of the two libraries, a particle system has been implemented. By profiling it has been determined that using instanced rendering it is currently possible to achieve higher performance using OpenGL ES. Based on the results and the theoretical part of the thesis it is possible to make a more informed decision between the two graphical libraries.

Complex Scene Rendering on Mobile Devices
Matýšek, Michal ; Polok, Lukáš (referee) ; Kajan, Rudolf (advisor)
This thesis presents optimization techniques for efficient rendering of complex scenes on mobile devices. The introductory part of the text describes Unity game engine and the topic of mobile game development using this tool. Then follows a presentation of important optimization principles and methods for terrain rendering, large scale rendering of animated objects, rendering of animated water surfaces and of other elements in the scenes. The described methods include both general principles of optimization and specific optimization approaches based on the features of Unity game engine. The implementation of presented methods is described and used in practice in the context of mobile strategy game development.

Graphics Demo with a Space Theme
Prajka, Martin ; Milet, Tomáš (referee) ; Herout, Adam (advisor)
This bachelor's thesis deals with the creation of graphics demo with unlimited size by using OpenGL. The thesis implements post-processing effects such as shadow mapping, bloom and gaussian blur. In addition, it describes particle system and camera animation. The demo is placed in space and it is separated into the three scenes. The end of the thesis is focused on the results of user's and performance tests.

Computer Game with Particle Systems
Vlková, Lenka ; Zemčík, Pavel (referee) ; Hradiš, Michal (advisor)
This bachelory thesis describes the design and the implementation of a 3D computer game with particle systems. The particle systems can be used for the simulation of a stochastic natural phenomena, for example fire and snow. In this thesis, you can find the description of the evolution of these systems, their uses and the description of the particular implementation. Other parts of the text are focused on another subjects involved in the game programming. The selection of an essential tool for game creation, a game engine, is crucial. Very important is also a collision detection that enables the movement of the objects in a game world and their responses to it. The design and the description of some parts of the implemented game is also a part of this work.

Real-Time Particle Simulations
Horváth, Zsolt ; Španěl, Michal (referee) ; Herout, Adam (advisor)
Particle simulations in real-time become reality only a few years before, when in computer science occured the idea of GPGPU. This new technology allows use the massive force of graphics card for general purposes. Today, the trend is to accelerate existing algorithms by rewriting into parallel form. On this priciple operate the particle systems too. An interesting area of particle systems are fluid simulations. The simulations are based on the theory of Navier-Stokes equations and their numerical solutions with SPH (Smoothed particle hydrodynamics). Liquids are part of everyday life, and therefore it is important to render them realistically. They are used in modern computer games and different visualizations that run in real time, therefore they must be quickly displayed.

Simple Game Using OpenGL
Čapek, Radovan ; Šiler, Ondřej (referee) ; Švub, Miroslav (advisor)
The work is focused on computer graphics and game developing. It describes physical model of a car behaviour and implements it in form of a racing game. The game loads 3ds models and includes many interesting visual techniques. Theoretical basics are discussed in the work. Besides the program itself, a tutorial describing how to programme this is also an output of the work.

Advanced Techniques Demo Using OpenGL
Buček, Antonín ; Přibyl, Jaroslav (referee) ; Herout, Adam (advisor)
This thesis demonstrates advanced techniques using OpenGL. The work is conceived as a demo without any size restrictions. It focuses on creating 3D world, which consists of inner rooms complex. Some additional interesting objects, lighting and shadows enrich the rooms. Particle systems, which were used to create explosions, smokes and some other particle effects are described in the thesis, too. 3D machine models fight between themselves using laser beams and form the story of the demo. Important part of the work is a movement model which is applied to both models and avatar. Sound track completes the demo.

Simulation of Large Particle Systems
Štambachr, Jakub ; Navrátil, Jan (referee) ; Juránek, Roman (advisor)
This bachelor thesis adresses the problem of large-scale particle system simulations. Its main goal is to create an efficient simulation model of cosmological N-body systems and its consequent testing. I chose to implement a version of Barnes-Hut Tree-Code algorithm, which meets the requirement for a high-speed simulation method. The tests carried out within the scope of this thesis imply that tree-code method is of a logarithmic complexity. As an output of this simulation model I present several videos, demonstrating in an illustrative fashion a functionality of the model.

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.
