Foil 6 VRML integration with the terrain data set

From General Collection of Foils for CRPC Annual Meeting CRPC Annual Meeting -- 14-17 May 1996 Argonne. by Geoffrey C. Fox
We will use the current output from ARPS in hdf format.
We will visualize the moisture variables.
  • We run an isosurface routine on the raw data, which generates output of cloud formation.
  • Will are developing a Java applet which will read in 3D data and determine isosurfaces.
    • The user will input the isosurface value from a WWW page running the applet.
    • The output of this applet will be VRML data that will be instantly rendered.
    • Also it can be stored in our Illustra object database
For the integration of the weather data to the existing 3D VRML terrain data set, we will use a 2D mask function which will determine where snow has fallen to a certain level.
VRML data will be stored in a database, allowing the user to interactively turn on and off the weather information over the terrain.
