FLARToolKit recognize the marker from input image  and calculate its orientation and position in 3D. It is an AS3 ported version of ARToolKit and it is also based on NyARToolkit, Java ported version of ARToolKit .

It includes helper classes for major flash 3D engines (Papervision3D, Away3D, Sandy, Alternativa3D), but you still need to draw your 3D graphics. Papervision3D is used in starter-kit.
