Matrix3D has the following row-vector syntax:

Note that because the fourth column is also accessible, the matrix allows developers to represent affine as well as non-affine transforms.

Matrices can be appended or prepended to other matrices. Appending matrix A to matrix B denotes a transformation by B and then by A:

// Multiplies a Vector3D by a Matrix3D using the static Multiply method.  
// Returns a Vector3D.

Vector3D vector1 = new Vector3D(20, 30, 40);
Matrix3D matrix1 = new Matrix3D(10, 10, 10, 0, 20, 20, 20, 0, 30, 30, 30, 0, 5, 10, 15, 1);
Vector3D vectorResult = new Vector3D();

vectorResult = Vector3D.Multiply(vector1,matrix1);
// vector Result is equal to (2000, 2000, 2000)

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
