Visualization for Ray-tracing
Vozár, Jaroslav ; Pelikán, Josef (advisor) ; Kondapaneni, Ivo (referee)
The aim of this work is to extend the existing image-rendering program based on ray- tracing. As this existing program is used to teach computer graphics at the Faculty of Mathematics and Physics of the Charles University, expanding tools provide the way to a simpler understanding of the substance. This includes statistics, analytical maps and especially the ability to track the rendering ray directly in the 3D scene. The last mentioned extension is essential and most useful for understanding deeper ray-tracing principles. In addition to facilitating the understanding of one of the main rendering techniques in computer graphics, these extensions will also help create homework for computer graphics subjects.
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.
Procedural Generation of Voxel Models
Hypeš, Tomáš ; Matýšek, Michal (referee) ; Milet, Tomáš (advisor)
This thesis deals with procedural generation techniques and its use in the creation of voxel models. The techniques that have been used are Perlin Noise, Voronoi diagram, L-systems etc. This knowledge is then used to create a world generator for computer game with open world. This game provides players with the ability to modify this world and use its creativity, for example, in building construction. The game, however, will not give to the player all options for free, but for example for build, he or she will first have to find and mine the material. The game has been written in programming language C++ with the use of libraries Boost, SDL and OpenGL.
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.
Procedural City
Dolejška, Daniel ; Chlubna, Tomáš (referee) ; Milet, Tomáš (advisor)
The goal of this thesis is to implement configurable tool (program), which will be able to build a model of a city. The program uses OpenGL library and principles of procedural generation for model creation. The generation process itself has a number of customizable variables, which have direct impact on the visuals of the models, their complexity and size. Created models can be exported and further modified in almost any 3D graphics software.
Rigid Body Simulation
Leitner, Denis ; Milet, Tomáš (referee) ; Chlubna, Tomáš (advisor)
This thesis deals with rigid body physics simulation in real time. It describes basic methods for collision detection between convex polyhedra, solving collisions and simulation of rigid body dynamics used in game development. Work also describes design and implementation of rigid body simulator written in C++ using OpenGL for rendering.
Sound Visualization
Švihálek, Filip ; Bečková, Zuzana (referee) ; Říha, Kamil (advisor)
This diploma thesis deals with computing parameters of sound signal. It includes methods for describing and implementing these parameters. In the practical part, the main programm is created which is computing and visualizing parameters. The program mis implemented in Microsoft Visual Studio with cooperation of Freeglut and BASS libraries.
Creation of the Graphic Library for VST Plug-Ins
Dufka, Filip ; Kříž, Petr (referee) ; Přikryl, Lubor (advisor)
Master‘s thesis covers use of graphical user interface in audio plug-ins. In first part structure and rendering techniques of audio plug-ins graphical libraries are described. Their efficiency and their way of memory utilization is questioned. Next part puts these techniques in comparison with the state of the art methods used in computer graphics and gaming industry. Their possible use in audio graphical interafaces is analyzed. In the following part, thesis finds solutions to uneffective methods in frequently used situations by presenting deferred shading into audio parameter editor with the goal of photorealistic rendering. Second introduced technique of „Knob Normal Maps“ reduces number of images needed for rendering of turning knob from hundereds to six with comparable results. Goal of diploma thesis was to create graphical library. Graphical library with name RealBox was created, and introduced techniques are the core features. Library reduces work needed to achieve graphical user interfaces for 2D and 3D cases of use. Full class and method documentation for RealBox library was assembled. Library was tested during creation of three VST plugins, with different approaches and emphasis on quick work and fine rendering. Graphical library offers new, faster way of creating audio plug-in interfaces.
Operator's station for Perseus mobile robot
Sabó, Marek ; Jílek, Tomáš (referee) ; Burian, František (advisor)
This thesis deals with the design and implementation of application for control of mobile robot. In the introductory section is discussed used platform GEARS-SMP, the principle of functionality of protocol for servo motors control, format M-JPEG and standard H.264. Further work is dedicated to analysis of designing user interface in robotic applications, available options for control devices and hardware used in remote controller. The following part focuses on the design of robotic application, especially on graphic user interface and virtual head-up display and follow-up implementation of created application in Raspberry Pi. In the end, thesis describes implemented software solution and compares resulting application with the created design.
Detection of object position
Baáš, Filip ; Janáková, Ilona (referee) ; Richter, Miloslav (advisor)
Master’s thesis deals with object pose estimation using monocular camera. As an object is considered every rigid, shape fixed entity with strong edges, ideally textureless. Object position in this work is represented by transformation matrix, which describes object translation and rotation towards world coordinate system. First chapter is dedicated to explanation of theory of geometric transformations and intrinsic and extrinsic parameters of camera. This chapter also describes detection algorithm Chamfer Matching, which is used in this work. Second chapter describes all development tools used in this work. Third, fourth and fifth chapter are dedicated to practical realization of this works goal and achieved results. Last chapter describes created application, that realizes known object pose estimation in scene.
