Hi Ko Ko,
You message to the list bounced because it was too long
(>40000 chars). It looked like the problem was a bunch
of appended HTML. Probably some NT craziness.
However, I am repeating your message because you found a
bug in visad.bom.ShadowBarbRealTupleTypeJ3D, which I have
fixed. You can get the fix at:
ftp://www.ssec.wisc.edu/pub/visad-2.0/ShadowBarbRealTupleTypeJ3D.java
Also, you might want to change:
z_map.setRange(0.0,0.1);
to something like:
z_map.setRange(-1.0,1.0);
Hopefully I will update the general source distribution
pretty soon.
CHeers,
Bill
Here's your message:
Hello Visaders
When I tried to stack up the flatfields on top of each
other, they appeared on the same Z-Plane instead of
appearing on different values of Z.I would appreciate
if someone help to solve this problem.
Ko Ko
