範例

下列範例示範如何將 結構乘 Point4D 以 Matrix3D 結構。

// 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 = Point4D.Multiply(point1, matrix1);
// pointResult is equal to (250, 270, 290, 4)

// Displaying Results
resultType = "Point4D";
syntaxString = "pointResult = Point4D.Multiply(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 = Point4D.Multiply(point1, matrix1)
' pointResult is equal to (250, 270, 290, 4)

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