定義

命名空間:

System.Windows.Media.Media3D

組件:

PresentationCore.dll

擷取將第一個指定 Vector3D 結構旋轉至第二個指定 Vector3D 結構所需的角度。

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

參數

vector1

Vector3D

要評估的第一個 Vector3D 結構。

vector2

Vector3D

要評估的第二個 Vector3D 結構。

傳回

Double

將 vector1 旋轉至 vector2 所需的角度，以度數為單位。

範例

下列範例示範如何取得兩 Vector3D 個 結構之間的角度。

                    // 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

備註

帶正負號的角度不會延伸到 3D 空間，因此會傳回介於 0 到 180 度之間的角度。
