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

參數

point

Point3D

要轉換的點。

matrix

Matrix3D

用來轉換 point 的矩陣。

傳回

Point3D

使用 point 轉換 matrix 的結果。

範例

下列範例示範如何使用多載乘法運算子，使用 Matrix3D 結構轉換 Point3D 結構。

// 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)
