Parametri

point: Point4D

Struttura Point4D da trasformare.

matrix: Matrix3D

Struttura Matrix3D di trasformazione.

Restituisce

Point4D

Restituisce il risultato della trasformazione di point in base a matrix.

Esempio

Nell'esempio seguente viene illustrato come usare l'operatore di moltiplicazione di overload per trasformare una Point4D struttura in base a una Matrix3D struttura.

// 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)
