Method Detail
clamp()method
public static function clamp(value:Number, min:Number, max:Number):Number

Moves value into the range between min and max.

Parameters

value:Number
 
min:Number
 
max:Number

Returns
Number
getNextPowerOfTwo()method 
public static function getNextPowerOfTwo(number:Number):int

Returns the next power of two that is equal to or bigger than the specified number.

Parameters

number:Number

Returns
int
intersectLineWithXYPlane()method 
public static function intersectLineWithXYPlane(pointA:Vector3D, pointB:Vector3D, out:Point = null):Point

Calculates the intersection point between the xy-plane and an infinite line that is defined by two 3D points in the same coordinate system.

Parameters

pointA:Vector3D
 
pointB:Vector3D
 
out:Point (default = null)

Returns
Point
isEquivalent()method 
public static function isEquivalent(a:Number, b:Number, epsilon:Number = 0.0001):Boolean

Indicates if two float (Number) values are equal, give or take epsilon.

Parameters

a:Number
 
b:Number
 
epsilon:Number (default = 0.0001)

Returns
Boolean
isPointInTriangle()method 
public static function isPointInTriangle(p:Point, a:Point, b:Point, c:Point):Boolean

Calculates if the point p is inside the triangle a-b-c.

Parameters

p:Point
 
a:Point
 
b:Point
 
c:Point

Returns
Boolean
max()method 
public static function max(a:Number, b:Number):Number

Returns the larger of the two values. Different to the native Math.max, this doesn't create any temporary objects when using the AOT compiler.

Parameters

a:Number
 
b:Number

Returns
Number
min()method 
public static function min(a:Number, b:Number):Number

Returns the smaller of the two values. Different to the native Math.min, this doesn't create any temporary objects when using the AOT compiler.

Parameters

a:Number
 
b:Number

Returns
Number
normalizeAngle()method 
public static function normalizeAngle(angle:Number):Number

Moves a radian angle into the range [-PI, +PI], while keeping the direction intact.

Parameters

angle:Number

Returns
Number
