make_spatial_index_nd()

MAYAFLUX_API std::unique_ptr< SpatialIndexND > MayaFlux::Kinesis::make_spatial_index_nd	(	float	cell_size,
		uint32_t	dimensions
	)

Create an N-dimensional spatial index with Euclidean squared distance.

Parameters

cell_size	Grid cell edge length (used only when dimensions <= 6).
dimensions	Number of dimensions in the coordinate space.
