This AR plugin is just a gyro sensor to help you control your camera rotation. A CameraViewer comes with it to help you turn on your camera as a background. CameraViewer is referenced from
It adds a design view to it and improves some of the code to make it more suitable for combining with Scene3D.
If you feel that the Primitives plugin that comes with it can create too few objects, you can contact me to purchase ExtendPrimitives or Loader.

Loader can help you open 3d files in OBJ, 3DS, MD2, ASC format.
