template<class T , typename REAL>
void pcl::recognition::VoxelStructure< T, REAL >::build ( const REAL  bounds[6],
int  num_of_voxels[3]

template<class T, typename REAL = float>
void pcl::recognition::VoxelStructure< T, REAL >::compute3dId ( int  linear_id,
int  id3d[3] 
) const [inline]

Converts a linear id to a 3D id, i.e., computes the integer 3D coordinates of a voxel from its position in the voxel array.

Parameters:
[in]linear_idthe position of the voxel in the internal voxel array.
[out]id3dan array of 3 integers for the integer coordinates of the voxel.

Saves pointers to the voxels which are neighbors of the voxels which contains 'p'.

The containing voxel is returned too. 'neighs' has to be an array of pointers with space for at least 27 pointers (27 = 3^3 which is the max number of neighbors). The
