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.

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.

Real-Time Rendering of a Scene With Many Pedestrians
Pfudl, Václav ; Milet, Tomáš (referee) ; Herout, Adam (advisor)
The aim of this thesis was to implement a software that would be able to render, simulate and record a scene with walking pedestrians in real-time, with emphasis on rendering level of realism. The output of the application could serve as an input test data for people counting systems or similar systems for video recognition. The problem was divided into three major subproblems: character animation, artificial intelligence for character movement and advanced rendering techniques. The character animation problem is solved by the skeletal animation of the model. To achieve the characters moving in a scene autonomously path finding(A* algorithm) and group behaviors(steering behaviors) were implemented. Realism in a scene is added by implemented methods such as normal-mapping, variance shadow-mapping, deffered rendering, skydome, lens flare effect and screen space ambient occlusion. Optimaliaztion of the rendering was implemented using octree data structure for space partitioning. Rendering stage of a scene can be easily parametrized through implemented GUI. Implemented application provides the user with easy way of setting a scene with walking pedestrians, setting its visualization and to record the result.

Demonstration and Benchmarking of Next-Gen Graphics APIs
Mainuš, Matěj ; Milet, Tomáš (referee) ; Herout, Adam (advisor)
The goal of master’s thesis was to demonstrate and benchmark peformance of Mantle and Vulkan APIs with different optimization methods. This thesis proposes a rendering toolkit with optimization methods based on parallel command buffer generating, persistent staging buffers mapping, minimal pipeline configuration and descriptor sets changing, device memory pre-allocating with managing and sharing between multiple resources. The result is reference implementation that could render dynamic scene with thousands of objects in real time.

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.
