Your data need to be organized in a regular xyz grid, not as just
a collection fo values are irregular xyz locations.

See Section 3.1 of the Vis5D README file to find out how to
put your data into Vis5D.

The folks at NCAR may have a version of Vis5D that creates VRML
scenes.

You can run Vis5D in the background via TCL scripts.  Some
folks run Vis5D from cron jobs this way.  However, you need
to have an X Display open.

Perhaps someone with more experience can give you more details.

Good luck,
Bill
