Point::DistanceSquared

inline T DistanceSquared(T x2, T y2) const;
inline T DistanceSquared(const Point<T> & pt) const;
inline T DistanceSquared() const;

Description

DistanceSquared calculates the distance squared between two points using the equation:

   (x2-x)^2 + (y2-y)^2

Parameters

Parameters	Description
T x2	The x coordinate of the point whose infinite distance to the current Point will be calculated.
T y2	The y coordinate of the point whose infinite distance to the current Point will be calculated.
const Point<T> & pt	A Point parameter whose x and y coordinates will act as x2 and y2 respectively in the equation above.

Return Value

A value containing the distance squared between two points.
