High dynamic range rendering of virtual 3D scenes
Goncearenco, Vadim ; Chlubna, Tomáš (referee) ; Pečiva, Jan (advisor)
Tato bakalářská práce je zaměřena na téma Vysokého Dynamického Rozsahu (HDR), konkrétně různých HDR technik, které jsou široce používány v oblasti počítačové grafiky. Navíc se zabývá Vulkan API a jeho aplikací pro HDR vykreslováni virtuálních 3D scén. Praktická část této práce je aplikace pro renderování 3D scén, jejímž účelem je demonstrovat praktickou implementaci popsaných HDR technik, jako jsou globální operátory mapování tónu (fotografické, filmové a založené na ACES), lokální operátor mapování tónu založený na bilaterálním filtru, dynamická adaptace oka, exposure fusion a pokročilý bloom efekt.

Evaluation glare of indoor and outdoor lighting systems
Rotrekl, Matěj ; Baxant, Petr (referee) ; Škoda, Jan (advisor)
Recent years have seen an increasing focus on electric energy consumption as well as ecology in relation to human health. It is crucial to maintain the so called lighting comfort which is influenced by a wide range of lighting parameters, including illuminance, brightness, balance of illuminance, and glare. Thanks to all these parameters we can design lighting systems in such a way as to prevent energy waste and far too rapid deterioration of eyesight. This study therefore focuses on glare evaluation of indoor and outdoor lighting systems. In order to comprehend the issue thoroughly, a detailed description of human eyes and their functions is provided, followed by definitions of glare and types of glare. An overview of different calculations for indoor and outdoor glare is provided, considering the evaluation of daylight glare in terms of complex lighting systems. The study mentions several options involving unconventional methods for measuring glare (brightness). In the analytical part of the study, outdoor glare on Kolejní Street and indoor glare at the Prof. Brauner Hall at VUT measurements were obtained using brightness analyzer (an unconventional method). The thesis is concluded with a comparison of the conventionally and unconventionally obtained measurements, considering their respective advantages.
