Hi all,
I have a 2D array (mountain elevation) and an image (trees,rocks,...) corresponding ot it. I need to overlap the image on the elevation information, along with the axis information and the capability of moving it around by the mouse in 3D.
Cgsurface (coyote's magic) seems to work well, however, I can't do anything with the mouse, nor rotating the axes from within the code (strange why this is not allowed). I am running a IDL 7.1, XQuarts 7.2.4, and already tried few terminal command remidies with no success fixing the cursor issue.
I see that xobjview works fine for my problem, however: no axis appear on the plot and th eimage is always in grey color!
Is there any know way to fix any of these problems? A third solution would be fine, too.
Please advise-thanks a lot for you help,
Steve

Really!? This command certainly rotates around in my IDL 7 version!
cgSurface, cgDemoData(2), ZScale=0.5, Texture_Image=cgDemoData(7), $
CTable=1, /Brewer, /Reverse, Title='2D Image as Texture'
Cheers,
David

Hmmmm, here's an update:
When I run the command line you sent from the terminal window, it works well. We I paste it into the idl interface and run from there, the mouse cursor does not work!
could it be something in the IDL preferences, strange....

UPDATE:
Very strange, but I found the issue. I have a breakpoint after the cgsurface command. When I remove that, it works. I though IDL works on a line by line basis. Oh man, little confusing...

When you STOP in IDL, everything stops, including widget event
processing. Chris reports that he has changed this behavior for IDL 8.3.
It will be interesting to see what unforeseen consequences that brings,
but it is probably a step in the right direction, since all the function
graphics routines will benefit from this change in behavior.
Cheers,
David

Thanks for info, this would indeed be an improvement and a change in the right direction.
