Does anyone have a fairly simple, standalone, interactive surface
viewer widget they'd be willin to share? I don't need all of the fancy
on-screen options like iTools, just a procedure like this
show_me_the_surface, data, group_leader=group_leader
where data is a 2d array representing z heights.
I just spent the last hour working with iSurface and then IDL's demo
program d_surfview.pro trying to make a very very simple, interactive
surface viewer. While these programs are powerful, they don't really
fit the bill for me.
Once I cut out 3/4 of the extra widgets, buttons, and event-handling
routines, from d_surfview, I had made it substantially closer to what
I'm after, but it's still a hack.
I don't need to have the ability to change color tables, set min/max
values, change to wireframe, . . . any of that. I just want to put up
a surface in an object window, in a top level widget, with readable
axes at the edges, and be able to rotate it with something like
IDLexRotator class, like trackball. (By the way, is IDLexRotator
undocumented?)
Thanks,
M. Katz

Hi M. Katz,
Perhaps you could do something like this:
IDL> oSurface = obj_new('IDLgrSurface', dist(30), style=2, color=[255,0,0])
IDL> oAxis0 = obj_new('IDLgrAxis', 0)
IDL> oAxis1 = obj_new('IDLgrAxis', 1)
IDL> oAxis2 = obj_new('IDLgrAxis', 2, location=[0,1])
IDL> oWindow = obj_new('IDLgrWindow', dimensions=[400,400])
IDL> oView = obj_new('IDLexObjView', [oAxis0, oAxis1, oAxis2, oSurface])
IDL> oView->Normalize, oWindow, /adjust_axes
IDL> xobjview, oView, xsize=400, ysize=400
The ability of xobjview to draw IDLexObjView objects is undocumented. The
oView->Normalize, /adjust_axes is undocumented too.
