Detailed Description

template<unsigned int VDimension = 3, typename TInput = Point< double, 3 >>
class itk::ConicShellInteriorExteriorSpatialFunction< VDimension, TInput >

Spatial function implementation of a conic shell.

We are creating search areas from BoundaryPoint1 in which to look for candidate BoundaryPoint2's with which to form core atoms. Assume the "worst case" that BoundaryPoint2 is somewhere in that search area pointing directly at BoundaryPoint1.

The search area (ConicShell?) from each BoundaryPoint1 has the following parameters:

DistanceMax and DistanceMin from the location of the BoundaryPoint

AngleMax from the line along the gradient at the boundary point. This is determined in n dimensions by taking the dot product of two vectors, (1) the normalized gradient at BoundaryPoint1 and (2) the normalized vector from BoundaryPoint1 to BoundaryPoint2.

If the absolute value of that dot product is greater than (1 - epsilon) then you are in the ConicShell. This epsilon is the same one determining face-to-faceness in the IEEE TMI paper.

Polarity, i.e. which direction along the gradient of BoundaryPoint1 you want to look.
