Constructor & Destructor Documentation

template<int D>
IMP::algebra::LogEmbeddingD< D >::LogEmbeddingD ( const BoundingBoxD< D > &  bb,
const VectorD< D > &  bases,
const Ints counts,
bool  bound_centers = false 
)

Embedding of a grid as a log-evenly distributed axis-aligned grid over the bounding box bb.

Parameters
bbthe bounding box in which the grid is embedded
basesbases[i] is a positive log base used for the grid spacing in dimension i. Set base[i] to 1 in order to create a standard evenly spaced grid along dimension i.
countscounts[i] is the number of discrete points in dimension i
bound_centersif true, then the bounding box tightly bounds the centers of the voxels, not their extents.

template<int D>
ExtendedGridIndexD<D> IMP::algebra::LogEmbeddingD< D >::get_extended_index ( const VectorD< D > &  o) const

Return the index that would contain the voxel if the grid extended there.

For example vectors below the "lower left" corner of the grid have indexes with all negative components. This operation will always succeed.

template<int D>
const VectorD<D>& IMP::algebra::LogEmbeddingD< D >::get_unit_cell ( ) const

Return the unit cell, relative to the origin.

That is, the unit cell is

BoundingBoxD<D>(get_zeros_vector_d<D>(),get_unit_cell());
