[Freegis-list] triangulation and contouring tools

[Ugo Taddei]

Hi,

check VisAD out:

http://www.ssec.wisc.edu/~billh/visad.html

and a derivative:

http://www.unidata.ucar.edu/software/idv/

you might need to write a wrapper or two, but you then get contours,
meshes etc, and some viz, too. There's also a Jython interface to simplify
the work.
Good luck,

Ugo
