Constructs the plane, from either four scalars of type pt or from a 3-dimensional vector (= normal) and a scalar.
Returns the distance from a point to the plane. Note: the plane must be normalized, the result can be negative.
Returns the distance from a point to the plane. Note: the plane does not have to be normalized, the result can be negative.
Normalizes the plane inplace.
Returns a normalized copy of the plane.
Holds the planes "constant" (HNF).
Base template for all plane-types.
