The major greatness of Away3D Lite lies in the fact that it utilizes Flash Player 10 math API completely and this speeds up the engine's performance considerably as Matrix3D calculations are processed by the Flash Player natively. Away3D Lite simplifies for you many of the math operations by presenting a set of common rotation and translation functions ...
