gridding non gridded data

[Teresa Sanchis <tsanchis(at)am.ub.es>]

Dear Colleagues, 

I'm trying to get a 3-D regular grid from my non gridded data.
First I tried with GRID3, but my results made no sense because I got
values much bigger or smaller than my non gridded values.
I have also been surfing in internet and I found a routine which uses
TSC (Triangular Shaped Cloud interpolation of irregularly gridded data
onto a regular grid). The problem is that I tested this routine and found
that it's necessary a great number of points to get a good gridding.
Unfortunately I only have few points (about a hundred) with many "holes"
between them.

I'm writing to you because maybe you know another type of 
gridding routine that could help me.

Thanks in advance
