 second vector Returns:
 the square of the distance between p1 and p2

orientation
public static <T extends CalculusFieldElement<T>> T orientation(FieldVector2D<T> p, FieldVector2D<T> q, FieldVector2D<T> r) Compute the orientation of a triplet of points. Type Parameters:
T
 the type of the field elements Parameters:
p
 first vector of the tripletq
 second vector of the tripletr
 third vector of the triplet Returns:
 a positive value if (p, q, r) defines a counterclockwise oriented triangle, a negative value if (p, q, r) defines a clockwise oriented triangle, and 0 if (p, q, r) are collinear or some points are equal
 Since:
 1.2
