Has anyone written something to programmatically rotate an iTools 3-D view and
save a sequence of images for animation (a la XOBJVIEW_ROTATE)?
I have learned the basics of doing iTool manipulations programmatically, but am
still very much a novice.
I would be quite happy to have something I can run from the command line,
passing in the iTool id, rotation axis, number of frames or rotation increment,
output directory, and file type (e.g., PNG).

Wow, you're right. I must admit I didn't actually run these two lines.
I figured out the identifier of the data space root a different way,
then assumed these two lines would work. FindIdentifiers seems a little
buggy to me, because the data space root object is definitely in the
tool container hierarchy, so I don't know why it doesn't show up in
FindIdentifiers.
So this encouraged me to look around some more, and I discovered a way
to do this that is actually documented (!), sort of.
If you can get access to the object that you want to rotate (like the
surface object in my example), you can call the GetManipulatorTarget
method on the surface to get the object that needs to actually be
rotated, like this:
oManipTarget=oSurface->GetManipulatorTarget()
if OBJ_VALID(oManipTarget) then $
oManipTarget->Rotate,axis,angle
In this case, oManipTarget will be the data space root object. I think
you still need to rotate the data space root, because if you rotate one
of the other dataspaces you might succeed in rotating the
visualization, but not the selection graphics.

Well, if you already have a reference to an object in the iTools
hierarchy (in fact, it can be ANY object that subclasses from
IDLitContainer), you can call its GetByIdentifier method. As long as
you pass in a full identifier, it will give you the object you want,
even if that object is in a different tool. For example (this is
contrived, but shows what I'm talking about):
iimage
void=itGetCurrent(TOOL=oImageTool)
iplot,IDENTIFIER=idPlot
So now you have the object reference to the iImage tool, and the
identifier to the iPlot tool. To get the object reference to the iPlot
tool:
oPlotTool=oImageTool->GetByIdentifier(idPlot)
Voila!
