I *think* he's just trying to get a true 3D field outta discrete x,y,z
data, which requires either 1) 'stacked' 2D interpolations/gridding or
2) a 3D interpol./gridding.

Search IDL help on triangulate and trigrid. But, I'll warn you in
advance, IDL's solution to 3D gridding is... how should i put this;
poor? It'd be educational to you to do a search for posts on '3D
interpolation', 3D gridding', 'trigrid' stuff like that and see the
frustration evolve.

Luck,
todd
