Foil 3 GIS in VRML

From Open Inventor Viewer for Terrain Data Rome Lab Quarterly Review for CIV -- June 28 96. by Krzysztof Walczak *
VRML as a language is sufficient for modeling of 3D data in GIS applications, however:
Modeling terrain in VRML produces enormous data sets, very difficult to maintain and transfer over the World-Wide Web
The functionality offered by general-purpose browsers is not satisfying:
  • No extensibility
  • No option to let user control visualization of data
  • No option to use data formats other than VRML (Open Inventor, binary form, etc.)
  • No option to implement interaction with other applications
