Preliminary Study of HGML-Based Virtual Scene Construction and Interaction Display

In spatial information networks which incorporate the client side dynamic aggregation services of G/S mode, in order to construct virtual scene that serves the real world, it requires extremely high fidelity and ability of real-time interaction of the environment. When dealing with data that have diverse, complex types and tremendous scale, consistent organization, management and data processing are essential. This article centers on introducing: synthesizing virtual reality environments based on HGML, 3D terrain models and 3D entity models, which are constructed through DEM and remote sensing data, and a preliminary research of the implementation and real-time interaction of the dynamic features.
