A estrutura Matrix3D de transformação.

Retornos

Point4D

Retorna o resultado da transformar point e matrix.

Exemplos

O exemplo a seguir mostra como multiplicar uma Point4D estrutura por uma Matrix3D estrutura.

// 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)
