Re: Program to visualize layers: revisited

Hi Ugo,

I'm sorry to say this is a bit confusing.  'M x N height points'
suggests that height is a function of latitude and longitude and
you are interested in surface attributes, but '2 x L x M x N points'
suggests that you are interested in attributes at L different depths
below the surface.
Are you only interested in the earth's surface, or are you
interested in soil type and other attributes at many different
depths below the surface?
What values of M, N and L are you using?
Do your data come from a simulation, or from observations?
I am am interested in the size and organization of your raw data,
before it comes into VisAD.

Actually, you can use Display.ZAxisOffset as a workaround, but
first I'd like to figure out the nature of your data.  Then it
will be easier to think about display mappings.
If you want, send me code (in Java, C or ?) that describes the
declaration of your data, before you have done any processing
on it.
