   import com.as3dmod.plugins.pv3d.LibraryPv3d;

2. Declare

   private var stack :ModifierStack;

3. Initialize

   stack = new ModifierStack(lib3d, mesh);

   Parameter	Default	Description
   lib3d	NONE	3D engine library
   mesh	NONE	3D object

4. Add

   stack.addModifier(new Bend(f, o, a));

   Parameter	Default	Description
   f	0	force bend 0 - 360 degrees (0 - 2)
   o	0.5	offset start (0 - 1)
   a	0	angle
