Research & Application Of 3DXML Standard In Cooperative Assembly

In the background of cooperative assembly, research on 3DXML standard and the application of it in cooperative assemble domain is done in this thesis.Firstly, based on the concept of 3DXML standard, the design principle,physical construction and logical contruction methods of the standard are discussed in detail. In order to solve the problem of re-appearing the procedure of cooperative assembly with 3DXML, a prototype system based on web services named CAPR is designed.Secondly, because of flaws of graphics modeling in 3DXML standard, a new 3D graphics modeling method is established, which makes content based search possible; because of lacking the dynamic attribute, a new 3D dynamic attribute modeling method is established. By adding dynamic attribute to 3D objects, the interative abilities are obtained on runtime.Finally, based on the extended standard, redesign and implementation of CAPR are made to prove the correctness and validity of the standard extended.
