Point4D.Subtract(Point4D, Point4D) 方法

定义

从一个 Point4D 结构中减去一个 Point4D 结构。Subtracts a Point4D structure from a Point4D structure.

public:
 static System::Windows::Media::Media3D::Point4D Subtract(System::Windows::Media::Media3D::Point4D point1, System::Windows::Media::Media3D::Point4D point2);
public static System.Windows.Media.Media3D.Point4D Subtract (System.Windows.Media.Media3D.Point4D point1, System.Windows.Media.Media3D.Point4D point2);
static member Subtract : System.Windows.Media.Media3D.Point4D * System.Windows.Media.Media3D.Point4D -> System.Windows.Media.Media3D.Point4D
Public Shared Function Subtract (point1 As Point4D, point2 As Point4D) As Point4D

参数

point1
Point4D

作为被减数的 Point4D 结构。The Point4D structure to be subtracted from.

point2
Point4D

要从 point1 中减去的 Point4D 结构。The Point4D structure to subtract from point1.

返回

Point4D

返回 point1point2 之间的差。Returns the difference between point1 and point2.

示例

下面的示例演示如何 Point4D 从结构中减去结构 Point4DThe following example shows how to subtract a Point4D structure from a Point4D structure.

// Subtracts a Point3D from a Point4D using the static Subtract method. 
// Returns a Point4D.

Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D point2 = new Point4D(15, 40, 60, 75);
Point4D pointResult = new Point4D();

pointResult = Point4D.Subtract(point1, point2);
// pointResult is equal to (-5, -35, -59, -71)

// Displaying Results
syntaxString = "pointResult = Point4D.Subtract(point1, point2);";
resultType = "Point4D";
operationString = "Subtracting a Vector3D from a Point4D";
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString);
' Subtracts a Point3D from a Point4D using the static Subtract method. 
' Returns a Point4D.

Dim point1 As New Point4D(10, 5, 1, 4)
Dim point2 As New Point4D(15, 40, 60, 75)
Dim pointResult As New Point4D()

pointResult = Point4D.Subtract(point1, point2)
' pointResult is equal to (-5, -35, -59, -71)

' Displaying Results
syntaxString = "pointResult = Point4D.Subtract(point1, point2)"
resultType = "Point4D"
operationString = "Subtracting a Vector3D from a Point4D"
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString)
