Ejemplos

En el ejemplo siguiente se muestra cómo usar el operador de multiplicación sobrecargada para transformar una Point3D estructura mediante una Matrix3D estructura.

// 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)
