Vector3D.AngleBetween(Vector3D, Vector3D) Method

Definition

Namespace:

System.Windows.Media.Media3D

Assembly:

PresentationCore.dll

Retrieves the angle required to rotate the first specified Vector3D structure into the second specified Vector3D structure.

public:
 static double AngleBetween(System::Windows::Media::Media3D::Vector3D vector1, System::Windows::Media::Media3D::Vector3D vector2);

public static double AngleBetween (System.Windows.Media.Media3D.Vector3D vector1, System.Windows.Media.Media3D.Vector3D vector2);

static member AngleBetween : System.Windows.Media.Media3D.Vector3D * System.Windows.Media.Media3D.Vector3D -> double

Public Shared Function AngleBetween (vector1 As Vector3D, vector2 As Vector3D) As Double

Parameters

vector1

Vector3D

The first Vector3D structure to evaluate.

vector2

Vector3D

The second Vector3D structure to evaluate.

Returns

Double

The angle in degrees needed to rotate vector1 into vector2.

Examples

The following example shows how to get the angle between two Vector3D structures.

                    // Calculates the angle between two Vector3Ds using the static AngleBetween method. 
                    // Returns a Double.

                    Vector3D vector1 = new Vector3D(20, 30, 40);
                    Vector3D vector2 = new Vector3D(45, 70, 80);
                    Double angleBetween;

                    angleBetween = Vector3D.AngleBetween(vector1, vector2 );
                    // angleBetween is approximately equal to 4.15129

' Calculates the angle between two Vector3Ds using the static AngleBetween method. 
' Returns a Double.

Dim vector1 As New Vector3D(20, 30, 40)
Dim vector2 As New Vector3D(45, 70, 80)
Dim angleBetween As Double

angleBetween = Vector3D.AngleBetween(vector1, vector2)
' angleBetween is approximately equal to 4.15129

Remarks

Signed angles do not extend into 3-D space, so an angle between 0 and 180 degrees is returned.
