Support system for distributed collaborative 3-D graphics design

We have been developing a support system which realizes collaborative designs of 3-D computer graphics through a computer network. When a collaborator sends a 3-D graphic, a 2-D image or a plain text to the server, the other collaborators will correctly obtain it without being aware of concurrency. By using this function, the collaborators can hold unfinished or finished graphics data in common. Using the Web mechanism, users can store the database server with the design products to retrieve and reuse them subsequently. This system helps design request persons and designers who works at distant places to produce, review and modify 3-D graphics with their creative ideas.
