Vector3D.AngleBetween(Vector3D, Vector3D) 方法

定义

命名空间:

System.Windows.Media.Media3D

程序集:

PresentationCore.dll

检索将第一个指定的 Vector3D 结构旋转为第二个指定的 Vector3D 结构所需的角度。

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

参数

vector1

Vector3D

要计算的第一个 Vector3D 结构。

vector2

Vector3D

要计算的第二个 Vector3D 结构。

返回

Double

将 vector1 旋转为 vector2 所需的角度（以度为单位）。

示例

下面的示例演示如何获取两 Vector3D 个结构之间的角度。

                    // 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

注解

带符号角度不会扩展到三维空间，因此返回 0 到 180 度之间的角度。
