Method for Three Dimensional Terrain Visualization on Internet

Study on 3d Terrain Visualization on Internet

With the analysis of the already existed theories of 3D terrain visualization, it is argued that how to use Digital Elevation Model to construct 3D terrain models on Internet, in the light of Level of Detail technology in this paper. Finally an application system is developed to real-time display and operates the terrain on Internet.

Cartographical Data Treatment Analysis for Real Time Three-Dimensional Terrain Visualization

The real time three-dimensional terrain visualization is associated to several characteristics, such as the video board exhibition. Moreover, the representation of a virtual scene is carried out through compositions of triangles that together confer a three-dimensional aspect to the scene. The available details in this scene are directly related to the number of triangles amount used in its rep...

Two-Dimensional Visualization for Internet Resource Discovery

Traditional information retrieval systems return documents in a list where documents are sorted according to their publication dates titles or similarities to the user query Users select interested documents by searching them through the returned list In a distributed environment documents are returned from more than one information server A simple document list is not e cient to present a larg...

Real-time Terrain Rendering and Visualization Based on Hierarchical Method

Three - dimensional Internet developments

This paper describes the application of Internet-based three-dimensional (3-D) user interfaces, comparing them with more traditional two-dimensional (2-D) interfaces. The modelling of 3-D worlds in the Virtual Reality Modelling Language (VRML) is described, together with an overview of VRML and its likely future direction. Multi-user shared environments, which enable Internet users to meet and ...
