Modifier and Type	Method and Description
static Point	center(BoundingBox bbox) Calculates the center of the given bounding box and returns a point representing that center.
static double	dotProduct(Point a, Point b) Computes the dot product of the given two points
static double	euclideanDistance(Point a, Point b) Calculates the Eucledian distance between two points a and b.
static GeneralPath	normalize(GeneralPath path)
static GeneralPath	toGeneralPath(Curve curve)
static Point	weightedSum(double weightA, Point a, double weightB, Point b) Adds the given points a and b, weighted by the respective weight, i.e.: weightA * a + weightB * b Attention! z may be NaN -- in this case, the weighted sum for z will be NaN too.

euclideanDistance

public static double euclideanDistance(Point a,
                                       Point b)

Returns:

weightedSum

public static Point weightedSum(double weightA,
                                Point a,
                                double weightB,
                                Point b)

Adds the given points a and b, weighted by the respective weight, i.e.:
weightA * a + weightB * b
Attention! z may be NaN -- in this case, the weighted sum for z will be NaN too.

Parameters:

weightA - scalar weight of vector a

a -

weightB - scalar weight of vector b

b -

Returns:

weightA * a + weightB * b

dotProduct

public static double dotProduct(Point a,
                                Point b)

Computes the dot product of the given two points

Parameters:

a -

b -

Returns:

a * b (i.e. a.x*b.x + a.y*b.y + a.z * b.z)
