Point3D.Multiply(Point3D, Matrix3D) 运算符

定义

命名空间:

System.Windows.Media.Media3D

程序集:

PresentationCore.dll

使用指定的 Point3D 结构转换指定的 Matrix3D 结构。

public:
 static System::Windows::Media::Media3D::Point3D operator *(System::Windows::Media::Media3D::Point3D point, System::Windows::Media::Media3D::Matrix3D matrix);

public static System.Windows.Media.Media3D.Point3D operator * (System.Windows.Media.Media3D.Point3D point, System.Windows.Media.Media3D.Matrix3D matrix);

static member ( * ) : System.Windows.Media.Media3D.Point3D * System.Windows.Media.Media3D.Matrix3D -> System.Windows.Media.Media3D.Point3D

Public Shared Operator * (point As Point3D, matrix As Matrix3D) As Point3D

参数

point

Point3D

要转换的点。

matrix

Matrix3D

用于变换 point 的矩阵。

返回

Point3D

用 point 变换 matrix 的结果。

示例

下面的示例演示如何使用重载乘法运算符通过 结构转换 Point3D 结构 Matrix3D 。

// Multiplies a Point3D by a Matrix.  
// Returns a Point3D.

Point3D point1 = new Point3D(10, 5, 1);
Point3D pointResult = new Point3D();
Matrix3D matrix1 = new Matrix3D(10, 10, 10, 0, 20, 20, 20, 0, 30, 30, 30, 0, 5, 10, 15, 1);

pointResult = point1 * matrix1;
// pointResult is equal to (235, 240, 245)

// Displaying Results
resultType = "Point3D";
syntaxString = "pointResult = point1 * matrix1;";
operationString = "Multiplying a Point3D by a Matrix3D";
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString);

' Multiplies a Point3D by a Matrix.  
' Returns a Point3D.

Dim point1 As New Point3D(10, 5, 1)
Dim pointResult As New Point3D()
Dim matrix1 As New Matrix3D(10, 10, 10, 0, 20, 20, 20, 0, 30, 30, 30, 0, 5, 10, 15, 1)

pointResult = point1 * matrix1
' pointResult is equal to (235, 240, 245)

' Displaying Results
resultType = "Point3D"
syntaxString = "pointResult = point1 * matrix1"
operationString = "Multiplying a Point3D by a Matrix3D"
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString)
