Terrain LoD Algorithm Implementation
Radil, Přemek ; Pečiva, Jan (referee) ; Bartoň, Radek (advisor)
This thesis discusses implementation of LoD terrain visualization algorithm Seamless Patches for GPU-Based Terrain Rendering as extension for Coin3D library. It presents procedures which this algorithm uses for displaying large terrain datasets. Entire terrain is composed of patches that are stored in patch hierarchy. Patch hierarchy is traversed during runtime to generate active patches based on observer's position. Each patch consists of predefined tiles and connection strips so it doesn't need to store any geometry. During render of tiles and strips, displacement shader is applied. This thesis also evaluates results achieved in sample application and suggests some modifications to further increase algorithm performance.

Interactive Animation Viewer and Editor
Ducháč, Michal ; Seeman, Michal (referee) ; Pečiva, Jan (advisor)
Since the introduction of high end graphical workstations, computer animation has quickly replaced the traditional means of animation. Nowadays computer animation has many applications e.g. video games, motion picture industry, media, weather forecasting and many others. This master thesis discusses various techniques used to created animations using computers. Keyframing, is the most common approach in computer animation. Borrowing its name from the concept of traditional hand animation, the workflow process remained the same. Basic principles of animation using key-frames are explained and an Interactive Animation Editor solution based on keyframing is proposed and the implementation of this editor is described. Editor uses the Kochanek-Bartels interpolation of values between each key-frame.
