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.
