I've attached a simple VisAD test program which creates and displays surfaces for layers given by (X, Y) --> (Z, property) transofrmations. It parses a simple file for the layers and shows them all in one display. I put this together for testing somethings, and it's really not a clean and entirely correct program. But it shows you how to use some features of VisAD for dealing with layers. I hope it helps. The program shows iso-contours displays, to see surfaces just comment out the addMap() for iscoutours (or write a clever gui for doing that and let me know:). You could also add a level transformation (like Bill was saying) if you want to display them one at a time, etc. I haven't figured out how to cleanly and efficiently construct a 3D set from a collection of 2D layers. Anyhow, it doesn't seem to be the right thing to do as you'll have distortions which may or may not be physically what you have. However, it would be nice to be able to do slicing on these layers. Even tinkering with the cliping planes might be useful. Seems to me the general problem of a cutting plane through some 2D layers given by (X, Y) -->(Z, p) should be easier than the general 3D volume slicing. -- mohamad Los Alamos National Laboratory CIC-8, MS B272 Los Alamos, NM 87545 (505) 665-4331
