Vector3D.AngleBetween Method

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

Namespace:  System.Windows.Media.Media3D
Assembly:  PresentationCore (in PresentationCore.dll)

public static double AngleBetween(
	Vector3D vector1,
	Vector3D vector2


Type: System.Windows.Media.Media3D.Vector3D
The first Vector3D structure to evaluate.
Type: System.Windows.Media.Media3D.Vector3D
The second Vector3D structure to evaluate.

Return Value

Type: System.Double
The angle in degrees needed to rotate vector1 into vector2.

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

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
