Vector3D.AngleBetween(Vector3D, Vector3D) Metod

Definition

Namnområde:
System.Windows.Media.Media3D
Sammansättning:
PresentationCore.dll

Hämtar den vinkel som krävs för att rotera den första angivna Vector3D strukturen till den andra angivna Vector3D strukturen.

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

Parametrar

vector1
Vector3D

Den första Vector3D strukturen som ska utvärderas.

vector2
Vector3D

Den andra Vector3D strukturen som ska utvärderas.

Returer

Double

Vinkeln i grader som behövs för att rotera vector1 till vector2.

Exempel

I följande exempel visas hur du hämtar vinkeln mellan två Vector3D strukturer.

                    // 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

Kommentarer

Signerade vinklar sträcker sig inte till 3D-utrymme, så en vinkel mellan 0 och 180 grader returneras.
