static member ( * ) : System.Windows.Media.Media3D.Point4D * System.Windows.Media.Media3D.Matrix3D -> System.Windows.Media.Media3D.Point4D

Public Shared Operator * (point As Point4D, matrix As Matrix3D) As Point4D

Parameters

point: Point4D

The Point4D structure to transform.

matrix: Matrix3D

The transformation Matrix3D structure.

Returns

Point4D

Returns the result of transforming point and matrix.

Examples

The following example shows how to use the overloaded multiplication operator to transform a Point4D structure by a Matrix3D structure.

// Multiplies a Point4D by a Matrix.  
// Returns a Point4D.

Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D pointResult = new Point4D();
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 (250, 270, 290, 4)

// Displaying Results
resultType = "Point4D";
syntaxString = "pointResult = point1 * matrix1;";
operationString = "Multiplying a Point4D by a Matrix3D";
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString);

' Multiplies a Point4D by a Matrix.  
' Returns a Point4D.

Dim point1 As New Point4D(10, 5, 1, 4)
Dim pointResult As New Point4D()
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 (250, 270, 290, 4)

' Displaying Results
resultType = "Point4D"
syntaxString = "pointResult = point1 * matrix1"
operationString = "Multiplying a Point4D by a Matrix3D"
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString)
