Detailed Description

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

Aim: transforms a signed cell c into a point corresponding to the signed cell of greater dimension that is directly incident to c.

Description of template class 'SCellToOuterPoint'

For instance, a linel is mapped into the direct incident pixel center and a surfel is mapped into the direct incident voxel center.
