Re: [ferret_users] Vis5D wind trajectories

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Steve,
The Ferret function writev5d was originally implemented as an external 
function in 2001 with minor upgrades in 2003, and was statically linked 
in the Ferret executable starting with Version 6.0 of Ferret. It 
incorporates Vis5D version 4.3
It takes a variable that's defined in Ferret, and makes calls to the 
Vis5D routines to write it to a file in the Vis5D format.

If you (or any of our users who might be interested) would like to take 
a look at the function and the code, it is contained in just a few 
files; the Fortran external function and the Vis5D library which is in 
c. If there are changes to be made, a new external function could be 
compiled.
