Hi everyone :)
I want to use this program to view roughly 100 regularly spaced points,
and their properties. The problem I seem to have is that the ORBS are
not spherical, but instead kind of ellipsoid. This is because the data
ranges for X, Y and Z are not comparable? What I mean is that the
xrange goes from 0-100, while the zrange from 0-0.01 for example. Any
idea on how to fix this? ( Im relatively new to IDL ;) )
The program can be found here:
http://www.dfanning.com/tip_examples/scatter_surface.pro
And I think the orbs are created in this section:
; Create the symbols for each point. This is almost certainly
; not the most efficient way if you have lots of points, but
; it works well for a reasonable number.
npts = N_Elements(x)
orbs=ObjArr(npts)
line=ObjArr(npts)
FOR j=0,npts-1 DO BEGIN
orbs[j] = Obj_New('ORB', Color=[r[zcolors[j]], g[zcolors[j]],
b[zcolors[j]]], $
Style=2, Radius=0.015, Pos=[x[j],y[j],z[j]])
line[j] = Obj_New('IDLgrPolyLine', [x[j], x[j]], [y[j], y[j]],
[min(z), z[j]], $
Color=[r[zcolors[j]], g[zcolors[j]], b[zcolors[j]]])
thisModel->Add, orbs[j]
thisModel->Add, line[j]
ENDFOR
Also, my data consists of 3 different sets. I would like to have 1
color for each set, but ofcourse different when compared to the other
2. Any hints on how to proceed on this?
Thanks in advance! :)

Oh, geez, hang on....
Now I can't even get my nifty example program to do
the right thing. Please forget this interruption and
go back to the interesting Mac problem going on this
morning. I'll get back to you when I figure it out again. :-(
Cheers,
David

Well, clearly, this explanation of what is going on
is as foggy as my understanding of the process, but
you know what I mean. :-)
