Subtraction(Vector3D, Vector3D)

从一个 Vector3D 结构中减去一个 Vector3D 结构。

public:
 static System::Windows::Media::Media3D::Vector3D operator -(System::Windows::Media::Media3D::Vector3D vector1, System::Windows::Media::Media3D::Vector3D vector2);

public static System.Windows.Media.Media3D.Vector3D operator - (System.Windows.Media.Media3D.Vector3D vector1, System.Windows.Media.Media3D.Vector3D vector2);

static member ( - ) : System.Windows.Media.Media3D.Vector3D * System.Windows.Media.Media3D.Vector3D -> System.Windows.Media.Media3D.Vector3D

Public Shared Operator - (vector1 As Vector3D, vector2 As Vector3D) As Vector3D

参数

vector1

Vector3D

作为被减数的 Vector3D 结构。

vector2

Vector3D

要从 vector1 中减去的 Vector3D 结构。

返回

Vector3D

vector2 减 vector1 所得的结果。

示例

下面的示例演示如何使用重载减法运算符从 Vector3D 结构中减去 Vector3D 结构。

// Subtracts a Vector3D from a Vector3D using the overloaded - operator.  
// Returns a Vector3D.

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

vectorResult = vector1 - vector2;
// vector Result is equal to (-25, -40, -40)

' Subtracts a Vector3D from a Vector3D using the overloaded - operator.  
' Returns a Vector3D.

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

vectorResult = vector1 - vector2
' vector Result is equal to (-25, -40, -40)

public:
 static System::Windows::Media::Media3D::Point3D operator -(System::Windows::Media::Media3D::Vector3D vector, System::Windows::Media::Media3D::Point3D point);

public static System.Windows.Media.Media3D.Point3D operator - (System.Windows.Media.Media3D.Vector3D vector, System.Windows.Media.Media3D.Point3D point);

static member ( - ) : System.Windows.Media.Media3D.Vector3D * System.Windows.Media.Media3D.Point3D -> System.Windows.Media.Media3D.Point3D

Public Shared Operator - (vector As Vector3D, point As Point3D) As Point3D

参数

vector

Vector3D

作为被减数的 Vector3D 结构。

point

Point3D

要从 vector 中减去的 Point3D 结构。

返回

Point3D

point 减 vector 所得的结果。

示例

下面的示例演示如何使用重载减法运算符从 Vector3D 结构中减去 Point3D 结构。

// Subtracts a Vector3D from a Point3D using the overloaded - operator.
// Returns a Point3D.

Point3D point1 = new Point3D(10, 5, 1);
Vector3D vector1 = new Vector3D(20, 30, 40);
Point3D pointResult = new Point3D();

// Subtracting the vector from the point
pointResult = vector1 - point1;

// pointResult is equal to (10, 25, 39)

' Subtracts a Vector3D from a Point3D using the overloaded - operator.
' Returns a Point3D.

Dim point1 As New Point3D(10, 5, 1)
Dim vector1 As New Vector3D(20, 30, 40)
Dim pointResult As New Point3D()

' Subtracting the vector from the point
pointResult = vector1 - point1

' pointResult is equal to (10, 25, 39)
