Detailed Description

template<typename CONTAINER_CELL>
class LibGeoDecomp::VoronoiMesher< CONTAINER_CELL >

VoronoiMesher is a utility class which helps when setting up an unstructured grid based on a Voronoi diagram.

It is meant to be embedded into an Initializer for setting up neighberhood relationships, element shapes, boundary lenghts and aeras.

It assumes that mesh generation is blocked into certain logical quadrants (container cells), and that edges betreen any two cells will always start/end in the same or adjacent quadrants.

template<typename CONTAINER_CELL >

virtual void LibGeoDecomp::VoronoiMesher< CONTAINER_CELL >::addCell	(	ContainerCellType *	container,
		const FloatCoord< DIM > &	center

void LibGeoDecomp::VoronoiMesher< CONTAINER_CELL >::addRandomCells	(	GridType *	grid,
		const Coord< DIM > &	coord,
		std::size_t	numCells
	)			[inline]

Adds a number of random cells to the grid cell (quadrant).

The seed of the random number generator will depend on the quadrant's logical coordinate to ensure consistency when initializing in parallel, across multiple nodes.
