java.lang.Object
  com.bramosystems.oss.player.core.client.geom.Matrix3D

public class Matrix3D
extends java.lang.Object

Implements a 4x4 matrix. The matrix is represented as an array of Vector3Ds Vx, Vy, Vz, Vw. The matrix notation is shown below:

         [ VxX  VyX  VzX  VwX ]
         [ VxY  VyY  VzY  VwY ]
         [ VxZ  VyZ  VzZ  VwZ ]
         [ VxW  VyW  VzW  VwW ]
