Detailed Description

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

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

Description of template class 'SCellToInnerPoint'

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