Detailed Description

template<typename KSpace>
class DGtal::functors::SCellToIncidentPoints< KSpace >

Aim: transforms a signed cell c into a pair of points corresponding to the signed cells of greater dimension that are indirectly and directly incident to c.

Description of template class 'SCellToIncidentPoints'

For instance, a linel is mapped into the pair of incident pixel centers and a surfel is mapped into the pair of incident voxel centers.

Template Parameters
