21	Generování komplexních procedurálních terénů na GPU / Generating Complex Procedural Terrains Using the GPU Ryba, Jan January 2011 (has links) Generating fully 3D terrains is a dificult task, meaning that we need to store a lot of data or do a lot of computing or both. We can reduce or completly eliminate the data srorage by using a procedural approch, but this is where the problem gets realy computationaly costly and the CUDA platform comes in. CUDA kernels runinng parallely on graphic accelerators can rapidly decrease time needed for computation, allowing even these complex calculations to work in real time or even better. Finding its use in game or movie industry.
22	Grafické intro 64kB s použitím OpenGL / Graphics Intro 64kB Using OpenGL Juránková, Markéta January 2010 (has links) The aim of the master's thesis is to create a graphic intro with the limited size of 64kB. Brief history of a demoscene and the graphics library OpenGL is introduced in the following text. The main part of the work is a description of minimal graphics techniques used in a creative process and their further application in the final programme.
23	Knihovna pro výpočet šumů používaných v procedurálním texturování / Library for Evaluation of Noises Used in Procedural Texturing Kučera, Ondřej Unknown Date (has links) The aim of the work is to describe procedural texturing and usage of a noise for creating textures of real materials. The reader will learn the fundamentals of the noise, its properties and a way of using it. Random numbers and interpolation methods are important parts of the noise evaluations, therefore there are chapters about random numbers generating and interpolation methods. Obviously, there is not missing the chapter, which is depicting properties and principles of several methods of creating noise. The main part of this work is effective implementation of library with a chosen noise methods, so next chapters are about choosing methods and design of the interface, implementation and many kinds of tests and optimalizations. Achieved results and final conclusions are at the end of this work.
24	Modelování a zobrazování pomocí blobů / Modelling and Rendering Using Blobs Baštek, Jozef January 2011 (has links) This thesis deals with blobs modeling and visualizing (iso-surfaces, implicit-surfaces). It includes implementation of full-featured editor of these objects. It provides real-time operations over surfaces. The work also contains its motivation - where this modeling technique comes from, required equations and computations needed for surface rendering and algorithms used for blobs visualization.
25	Grafické demo s inverzní kinematikou / Graphics Demo with Inverse Kinematics Kárníková, Pavlína January 2010 (has links) This work deals with the creation of a graphic demo with the use of inverse kinematics. It explains the motivations that led to the creation of the demo; it briefly mentions the history of the demo as well as the principles of animation. It describes in detail the fundamentals of inverse kinematics as well as the terminology needed for the understanding of inverse kinematics. It also includes some selected algorithms. The issue of inverse kinematics is further developed in the part of the work where the principles of skinning are being described. The principles of the collision detection are also mentioned here. The conclusion consists of a detailed explanation of some of the techniques used in graphic demo, such as the L-systems or procedural textures.
26	Exploring feasibility of reinforcement learning flight route planning / Undersökning av använding av förstärkningsinlärning för flyruttsplannering Wickman, Axel January 2021 (has links) This thesis explores and compares traditional and reinforcement learning (RL) methods of performing 2D flight path planning in 3D space. A wide overview of natural, classic, and learning approaches to planning s done in conjunction with a review of some general recurring problems and tradeoffs that appear within planning. This general background then serves as a basis for motivating different possible solutions for this specific problem. These solutions are implemented, together with a testbed inform of a parallelizable simulation environment. This environment makes use of random world generation and physics combined with an aerodynamical model. An A* planner, a local RL planner, and a global RL planner are developed and compared against each other in terms of performance, speed, and general behavior. An autopilot model is also trained and used both to measure flight feasibility and to constrain the planners to followable paths. All planners were partially successful, with the global planner exhibiting the highest overall performance. The RL planners were also found to be more reliable in terms of both speed and followability because of their ability to leave difficult decisions to the autopilot. From this it is concluded that machine learning in general, and reinforcement learning in particular, is a promising future avenue for solving the problem of flight route planning in dangerous environments.
