Esempio

Nell'esempio seguente viene illustrato come utilizzare l'operatore di moltiplicazione di overload per trasformare una Point3D struttura utilizzando una Matrix3D struttura.The following example shows how to use the overloaded multiplication operator to transform a Point3D structure by using a Matrix3D structure.

// 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)
