I'm no salesperson either, but my understanding is that the unbundled
package "GT-Grid" from VNI is for just this type of data. I'm not sure what
constraints it places on the irregularity of the data, but I'm told it is
much better than the "stock" 4.0.1 CL routines.
I have been thinking of adding this on, since I deal with quite a bit of
irregulary spaced 3/4D volumetric data, so does anyone have any experience
they could enlighten me with?
