## Definition

Refines
  `AdaptableQuinaryFunction`

See also
  `CGAL::Weighted_point_3<Kernel>`
  `ComputePowerProduct_3` for the definitions of power distance and orthogonality.

## Operations
A model of this concept must provide:
Kernel::FT | operator() (const Kernel::Weighted_point_3 &p, const Kernel::Weighted_point_3 &q, const Kernel::Weighted_point_3 &r, const Kernel::Weighted_point_3 &s, const Kernel::Weighted_point_3 &t) const
| returns the squared radius of the sphere centered in `t` and orthogonal to the sphere orthogonal to `p`, `q`, `r` ,and `s`.
