Static Methods

atan2(double y, double x) double
Returns the angle of two vector components. The result is less acurate than the standard atan2 function in the math package.
distanceBetweenPoints(Offset a, Offset b) double
Approximates the distance between two points. The returned value can be up to 6% wrong in the worst case.
filter(double a, double b, double filterFactor) double
Interpolates a double between a and b according to the filterFactor, which should be in the range of 0.0 to 1.0.
filterPoint(Offset a, Offset b, double filterFactor) Offset
Interpolates a Point between a and b according to the filterFactor, which should be in the range of 0.0 to 1.0.
lineIntersection(Offset p0, Offset p1, Offset q0, Offset q1) Offset
Returns the intersection between two line segmentss defined by p0, p1 and q0, q1. If the lines are not intersecting null is returned.
