Tessellation of trimmed NURBS surfaces.
Safko, Martin ; Šír, Zbyněk (advisor) ; Pelikán, Josef (referee)
Tessellation of trimmed NURBS surfaces is classical problem in CAD/CAM, with long history and huge amount of research developed so far. We present and describe a tessellation algorithm suitable for visualization purposes in either offline or online setting and present our results. We also provide pointers to litera- ture and to tessellation algorithms for simulation. We discuss relevant definitions and procedures necessary to work with CAD data and try to familiarize it for people outside the industry. 1

Implementation of a tone mapping operator for scotopic viewing conditions
Safko, Martin ; Wilkie, Alexander (advisor) ; Kratochvíl, Miroslav (referee)
Creating night-time images and movies that look plausible has been a problem in the industry since the creation of camera. To capture an image we need enough light to create a measurable quantity on a camera sensor. For this reason, shooting at night was not possible until sensors sensitive enough were developed and even then the captured images do not look realistic. Movie industry circumvent these issues by manually color correcting the footage in post-production. We implement an algorithm presented in a 2011 SIGGRAPH paper capable of solving this problem in a psycho-physically plausible and consistent way for spectral images and also augment it by a technique taken from a paper by INRIA. 1
