Exemples

L’exemple suivant montre comment utiliser l’opérateur de multiplication surchargé pour transformer une Point4D structure par une 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)
