Method Detail

toGeneralPath

public static java.awt.geom.GeneralPath toGeneralPath(Curve curve)

Parameters:

curve -

Returns:

normalize

public static java.awt.geom.GeneralPath normalize(java.awt.geom.GeneralPath path)

Parameters:

path -

Returns:

center

public static Point center(BoundingBox bbox)

Calculates the center of the given bounding box and returns a point representing that center.

Parameters:

bbox -

Returns:

euclideanDistance

public static double euclideanDistance(Point a,
                                       Point b)

Calculates the Eucledian distance between two points a and b.

Parameters:

a -

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)
