Method for downloading selectable progressive mesh models under the environment of World Wide Web

摘要

A method for downloading selectable progressive mesh models under the environment of World Wide Web is disclosed. The converted progressive mesh model is stored in a database installed in the World Wide Web server by a relational database format. The LOD ID of a progressive mesh model is used as a primary key of the database. By using the existing program service, the Mesh data of some layer can be requested in a network by a HTTP with LOD ID (LID). Therefore, under the current World Wide Web environment, no new server program is necessary, while only the current service program of CGI/ASP/PHP is used to download the data of progressive mesh model of some layer.
