AVL.AngleBetweenVectors(AvlNet.Vector2D, AvlNet.Vector2D, AvlNet.RotationDirection?, float, float)

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax


public static void AngleBetweenVectors(
	AvlNet.Vector2D inVector1,
	AvlNet.Vector2D inVector2,
	AvlNet.RotationDirection? inRotationDirection,
	out float outAbsoluteAngle,
	out float outDirectedAngle
)

Parameters

inVector1
Type: AvlNet.Vector2D
inVector2
Type: AvlNet.Vector2D
inRotationDirection
Type: System.Nullable<AvlNet.RotationDirection>
outAbsoluteAngle
Type: System.Single
outDirectedAngle
Type: System.Single

Description

Note that because of inaccuracies of floating-point arithmetic, some geometric operations (including this one) may lead to unpredictable results for degenerated cases. In this filter such a case occurs when a zero vector is given on input.

Examples

AngleBetweenVectors performed on two vectors: inVector1 DeltaX = 10, DeltaY = 10, inVector2 DeltaX = -5, DeltaY = 5, inRotationDirection = CounterClockwise.
outAbsoluteAngle returns 270, and outDirectedAngle returns -270.
