Static Methods

getNextPowerOfTwo(num value) → int

Calculates the next power of two for the given value. If value is already a power of two, it is returned. If value is not a power of two, the smallest power of two greater than value is returned.

isEquivalent(double a, double b, [double epsilon = .0001]) → bool

Determines if two floating-point numbers are equivalent within a given epsilon value.

isPointInTriangle(GPoint point, GPoint a, GPoint b, GPoint c) → bool

Determines whether a given point is inside a triangle defined by three other points (a, b, c).

normalizeAngle(double angle) → double

Normalizes the given angle (in radians) to the range of -pi to pi.

shortRotation(double rotation) → double

Shortens the given rotation angle to the range of -pi to pi.

Constants

halfPi → const double

Half of the value of pi.

pi2 → const double

The value of 2 times pi.
