Specialization of Boundary<dim>, which places the new point on the boundary of a ball in arbitrary dimension. It works by projecting the point in the middle of the old points onto the ball. The middle is defined as the arithmetic mean of the points.
The center of the ball and its radius may be given upon construction of an object of this type. They default to the origin and a radius of 1.0.
This class is derived from StraightBoundary rather than from Boundary, which would seem natural, since this way we can use the StraightBoundary::in_between() function.

const Point<spacedim> HyperBallBoundary< dim, spacedim >::center [protected] |
Center point of the hyperball.
Definition at line 487 of file tria_boundary_lib.h.
const double HyperBallBoundary< dim, spacedim >::radius [protected] |
Radius of the hyperball.
Definition at line 492 of file tria_boundary_lib.h.
bool HyperBallBoundary< dim, spacedim >::compute_radius_automatically [protected] |
This flag is false for this class and for all derived classes that set the radius by the constructor. For example this flag is false for the HalfHyperBallBoundary class but it is true for the HyperShellBoundary class, for example. The latter class doesn't get its radii by the constructor but need to compute the radii automatically each time one of the virtual functions is called.
