The end result of the positioning, rotating, and scaling a 3D object can be described as a single 4x4 matrix called the transform matrix.

Matrices are represented by the Matrix3D class in the flash.geom package. It is possible to manipulate a transform matrix directly, and then pass it to a 3D object via the transform property defined in the Object3D class. However, it is generally more convenient to use the listed functions to transform a 3D object rather than modifying the transform matrix directly.
