4K Video Player for Virtual Reality
Chvíla, Václav ; Matýšek, Michal (referee) ; Kobrtek, Jozef (advisor)
The subject of this work is the implementation of 4K video player for virtual reality. Theoretical part describes the origin of 360° videos, their compressions and rendering. In design of application was choosed solution with OpenGL, OpenVR, Qt libraries and commercial codec jpeg2000 developed by Comprimato company and for virtual reality device the HTC Vive headset. In part of implementation is analysed problem of shared video memory between libraries and discusses optimalization of the video player. Application was tested in perfomance and by users.

Rendering of Shadows in a Scene with DirectX
Kobrtek, Jozef ; Havel, Jiří (referee) ; Navrátil, Jan (advisor)
This work discusses shadowing methods, analyses them and describes implementation in DirectX 11 API. Theoretical part describes historical evolution of shadow usage in 3D applications and also analyzes shadowing algorithms. This work compares 2 variants of shadow mapping algorithm for omnidirectional lights, based on cube mapping and paraboloid projection, on demo application using quality, performance and implementation aspects.
