Abstract
Tato diplomová práce se zabývá implementací adaptivní datové struktury octree pro knihovnu TNL v programovacím jazyce C++. Tato struktura se požívá pro efektivní práci s trojrozměrnými objekty v oblastech jako počítačová grafika a vědecké výpočty. Také byla implementována paralelní verze octree pomocí rozhraní MPI. V práci jsou prozkoumány různé metody implementace octree, které jsou následně srovnány. Nejlepší efektivitu podle výsledků práce vykazuje klasický octree a lineární octree používající hash tabulku hopscotch.
This thesis deals with the implementation of the adaptive octree data structure for the TNL library in the C++ programming language. This structure is used for efficient work with three-dimensional objects in fields such as computer graphics and scientific computing. A parallel version of the octree was also implemented using the MPI interface. The thesis explores various methods of implementing octrees, which are then compared. According to the results of the study, the classic octree and the linear octree using a hopscotch hash table show the best efficiency.
