Constructor & Destructor Documentation

HilbertCompareFunctor()

walberla::mesa_pd::sorting::HilbertCompareFunctor::HilbertCompareFunctor	(	const math::AABB &	domain,
		const uint_t	cells )

Subdivides a domain into cells and arranges the cells according to the sfc.

The position within the sfc gives the particles their weight.

Parameters

domain	domain which should be partitioned into cells
cells	number of cells in every direction.

Attention

cells has to be a power of 2!
