Research On 3D Model Conversion Engine And Its Application

With the development of Internet technique, VR technique and 3D Modeling technique, it has become a developmental direction of 3D VR environment, and it will be a trend for sharing integration system depending on Web Service. 3D data are the basis of the 3D application system, but now more and more 3D spatial data are placed on externally separated computers, and at the same time there are a lot of differences in 3D data store models and data store files, so that the question for multi-source data sharing should be resolved. Although it's a difficult point for sharing and integrating 3D data, the data engine technique and VRGIS technique provide the new idea and method for sharing and integrating 3D spatial data.The thesis encircled the files sharing and conversion of multi-source 3D data, researching on the multi-source 3D data integration nowadays' situation and further development, based on the 2D sharing method, analyzed several models of 3D data integration, and raised the facing problem for multi-source data integration. This thesis emphasized more on the conversion and sharing of 3D files and analyzed the differences of multi-source 3D data which appeared on the internet, provided the 3D data integration method based on the data conversion model and raised the concept of "3D data conversion engine ",designed the general 3D data spatial database and main data analysis component and output component , realized the inter-conversion of some main 3D data ,based on that studied more on the 3D data conversion integration for web Service, talked its possibility and its application on web environment so that done some tries of the 3D data integration for later study.Based on that, this thesis introduced the key technique for application of the diversity 3D data multi-source integration such as 3D spatial database technique, data pre-procession technique and designed the 3D data application engine frame for multi-source 3D data integration visualization, researched and tried to design the technical method for multi-source 3D data integration. At last, this thesis's research result indicated that the method is feasible, and it's reliable of the 3D data engine application system frame.
