Digital Shoemaking-oriented Management Of Three-dimensional Shoe Lasts' Resources

The rapid development of computer graphics and network technology lays a solid foundation of shoemaking industry's stepping forward digitization. Aim at strengthening management of shoe lasts' resources and providing customers with real time shoe lasts' data, this project develops the digital shoemaking-oriented management system of three-dimensional shoe lasts' resources, which enables enterprises to store shoe lasts' data described by the digitized form and customers to browse the three-dimensional shape and parameters of various kinds of lasts on line.The whole system consists of the server-side and client-side. The server-side software contains two versions, one is provided for the administrator and the other is for common operators. The administrator version is deployed in the server and it is responsible for carrying out many important functions including the compaction and storage of three-dimensional shoe lasts' data, the local rendering and criteria query of three-dimensional shoe lasts' data, the import and export of customers' orders between the database and excel files, the processing and reply of client-side's requests and so on. And the operator version is installed in the host machines of common operators. The communication protocol between server-side and client-side is TCP/IP, which ensures the reliability of connection. The client-side works like this: First, it submits the local requests to the server. Then, it downloads the data of three-dimensional shoe last from the server. Finally, it renders the three-dimensional and two-dimensional shape of last. Based on SQL Server 2005, we design the backend database which is used for storing all kinds of data. Visual Studio 2005 provides the integrated development environment which makes it convenient for us to develop the applications of system.Besides, we also utilize other advanced technologies such as ADO, B-spline surface and so on. Based on the requirements of enterprise and customers, the system constructs an excellent platform for managing shoe lasts' resources.
