Abstract
Many applications, including 3D Geographic Information Systems (GIS)
and flight simulation, rely on 3D terrain models. A system that supports
these applications should ideally provide real-time interactive rendering
of section of a large set of terrain data that may be accessed remotely
using a client/server system. We present a Web-based system for
interactive 3D terrain rendering using Virtual Reality Modeling
Language (VRML), a Web standard for presenting 3D virtual worlds.
We describe an implementation of a 3D terrain model in VRML 1.0, and
a design for improving the implementation using the new features
available in VRML 2.0. We discuss the advantages and disadvantages of
VRML for constructing, accessing and visualizing 3D terrain models.
