[away3d] addFace in Away3D Lite

[Crabar]

Hello!

I began to translate my project with away3d on away3dLite. In away3d I
form my object extended by Mesh, i'm adding faces like this (form quad
by 2 triangles (4 dots)):

                        for (var j:int = 0; j<(Number3DArray.length-1); j++)
                        {
                                        for (var i:int = 0; i< 
(Number3DArray[j] as
Vector.<Number3D>).length-1; i++)
                                        {
                                                // first triangle of quad
                                                var FirstFace:Face = new Face();
                                                FirstFace.v0 = 
(Number3DArray[j] as Vector.<Number3D>)[i];
                                                FirstFace.v1 = 
(Number3DArray[j] as Vector.<Number3D>)[i+1];
                                                FirstFace.v2 = 
(Number3DArray[j+1] as Vector.<Number3D>)[i];
                                                this.addFace(FirstFace);
                                                FirstFace = null;
                                                // second triangle of quad
                                                var SecondFace:Face = new 
Face();
                                                SecondFace.v0 = 
(Number3DArray[j] as Vector.<Number3D>)[i+1];
                                                SecondFace.v1 = 
(Number3DArray[j+1] as Vector.<Number3D>)[i+1];
                                                SecondFace.v2 = 
(Number3DArray[j+1] as Vector.<Number3D>)[i];
                                                this.addFace(SecondFace);
                                                SecondFace = null;
                                        }
                        }

How do i add faces to mesh in away3dlite, that would get the same
object?

Thanks!
