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
aandbaccording to thefilterFactor, which should be in the range of 0.0 to 1.0. -
filterPoint(
Offset a, Offset b, double filterFactor) → Offset -
Interpolates a Point between
aandbaccording to thefilterFactor, 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.
