Fly over Rugged Planet
 Pospíšil, Petr ; Chudý, Peter (referee) ; Jošth, Radovan (advisor)
This thesis deals with a 3D visualization of the Earth´s surface in real time. A significant part is dedicated to the buffering of the large amount of data (a height map and textures of Earth) and its effective reading from hard disk directly to the memory of a graphic card. Individual levels of detail of the Earth´s surface are made by GeoMipMapping. The algorithms "horizon" and "frustum culling" are used, which cut off the hidden parts of the planet. The application of the height data is based on a custom algorithm calculating the data directly in the graphic card, in assistance with its vertex and geometry shaders.
