Detailed Description

template<class OBJECT_TYPE, class SCALAR_TYPE>
class vcg::PerfectSpatialHashing< OBJECT_TYPE, SCALAR_TYPE >::BinaryImage

This class is used to encode the sparsity of the dataset. Since the hash table stores data associated with a sparse subset of the domain, it may be necessary to determine if an arbitrary query point lies in this defined domain.

template<class OBJECT_TYPE , class SCALAR_TYPE >

void vcg::PerfectSpatialHashing< OBJECT_TYPE, SCALAR_TYPE >::BinaryImage::Allocate

(

const int

size

)

[inline]

Allocate the space necessary to encode the distribution of the dataset over the domain.

Parameters:

[in]

size

The resolution on each dimension of the bitmap.

Definition at line 957 of file perfect_spatial_hashing.h.

template<class OBJECT_TYPE , class SCALAR_TYPE >

void vcg::PerfectSpatialHashing< OBJECT_TYPE, SCALAR_TYPE >::BinaryImage::Clear

(

void

)

[inline]

Removes all flags from the bitmap. This function is called after a failed attempt to create the offset-table.

bool vcg::PerfectSpatialHashing< OBJECT_TYPE, SCALAR_TYPE >::BinaryImage::ContainsData

(

const typename UniformGrid::CellCoordinate &

at

)

const [inline]

Checks if a portion of the dataset fall inside the UniformGrid cell having coordinate at.

Parameters:

[in]

at

The index of the UniformGrid cell to check.

Returns:

true if and only if a portion of the dataset in included in this UniformGrid cell.
