Abstract :
In this paper, an approach is presented for terrain visualization on the Internet, in which the NURBS method is used for surface fitting conforming to the X3D standard. On the basis of centripetal and cross-sectional models, the DEM can be transformed to an X3D model for Internet transmission. The approach is able to compress data but increase display resolution which can be viewed as the fundamental step of Web3D modeling and transmission.
