Procedural Texture Generator
Doroshenko, Ilya ; Karas, Matej (referee) ; Milet, Tomáš (advisor)
Textures are an essential part of modern 2D and 3D rendering. The most prominent texturing techniques are Texture Mapping and Procedural Generation. Both techniques have their set of demands on computational resources. Procedural generation provides rich detail resolution without memory consumption, but also requires processing power. Texture Mapping is quick to process, but images, that the texture consists of are using a lot of space in memory and have finite resolution and sets of complications around algorithms that try to overcome that problem. This thesis discusses techniques of texture generation their interchangeability and applications. Result is an extensible application, that can produce texture maps from algorithms and can export algorithms to be used in procedural shading techniques.

Response to abiotic stress in plants growing in green façades of temperate urban environment
Hrochová, Růžena ; Lhotáková, Zuzana (advisor) ; Havelková, Lenka (referee)
With increasing urbanization the temperature of cities is increasing and an effect of urban heat island arises. Vegetation, particularly vertical greenery systems: facades and walls, is mitigating urban heat island and reducing temperature. The aim of this work was to define these systems, their effects on the urban microclimate, to create an overview of the most used plants for greenery systems and to summarize their reactions to abiotic stresses of cities in a temperate region. Mediterranean studies were used in this work due to the scarcity of temperate climate research, which results could become valuable with climate change. Selecting proper vegetation can be done using habitat template, plants that are acclimated or adapted to the urban environment. Plants affect the urban microclimate through shading and transpirational cooling, which ideally contribute to reducing the heat island effect with optimal irrigation. Stressors followed in this work were drought, high temperature and irradiance, air pollution and salinity. To all these stressors plants reacted with limiting physiological functions and reducing growth. The common reaction was a decrease photosynthesis rate and chlorophyll content. Ractions of plants of vertical greenery systems to different stressors and their combinations are...

Interactive web applications supporting education of 3D graphics
Priščák, Jaroslav ; Mokrý, Ondřej (referee) ; Rajmic, Pavel (advisor)
The use of interactive web applications has the potential to significantly improve the teaching of 3D computer graphics. By taking advantage of the convenience and accessibility of the web, these applications can provide students with more engaging and interactive learning. This thesis explores the development of such applications to help understand the fundamentals required for calculations such as normal vectors and tangent planes. Further, the thesis describes Phong's illumination model, the environmental and material parameters that affect the resulting light reflection. It then describes the different shading models such as flat, Gouraud and Phong shading models, describing the various advantages and disadvantages, the differences in computational complexity in determining the color of a fragment and individual pixels. It also explains the code on which these applets are built.

Processing of territorial study as a basis for urban plan
ČERMÁKOVÁ, Veronika
The diploma thesis is focused on the preparation of a territorial study and the related issues of territorial planning. The chosen locality for the development of the study is the village of Myslkovice. Through the analysis, several problems were found to be solved. This is a lack of living space, a threat to the popular public space in front of the local castle and noise and dust pollution around the production areas. Each of the locations requires a different solution and all are described in detail in this thesis. In addition to the solution and description of the affected areas, the work also inc-ludes a literature search of the chosen issue and a detailed description of the area. The conclusion of the work is the recommendation of resulting strategies to improve the analyzed problems.

Ecological differences between herbs and woody plants, and evolution of the herbaceous habit
Klimeš, Adam ; Herben, Tomáš (advisor) ; Lens, Frederic (referee) ; Těšitel, Jakub (referee)
Ecological differences between herbs and woody plants, and evolution of the herbaceous habit Adam Klimeš, doctoral thesis Abstract Flowering plants (angiosperms), which make up most present-day vegetation, were originally woody. While flowering plants have repeatedly given rise to herbaceous lineages since their first appearance, we lack a clear explanation for these common evolutionary events. Freezing temperatures and drought periods have been proposed as factors which had caused huge success of the younger growth form but the evidence is very limited and not in favour of these hypotheses. In this thesis, we aimed to build the foundations of research on the evolution of herbs. We outlined new potential drivers of the evolution of herbs, suggested solutions to some methodological challenges and provided evidence about differences between herbs and woody plants relevant to the hypotheses on herb evolution. To this end, we used common garden experiments with young plants of both growth forms and global trait data from public databases which we evaluated using phylogenetic comparative techniques. Annuality of aboveground biomass and fast life-strategy of herbs are characteristics which differentiate them from woody plants and which in some conditions are expected to be behind their success. Apart from the...
