I don't know of a way to programmatically add an IDLgrMODEL
object to an iTool. The iTools seem to be able to import
models as an "IDL graphics object" (although see the other
iTool thread today about fatal errors that result when you
exit a tool for which you have imported at least some models).
All I can find are ways to import *data* into an iTool programmatically.
I presume that models are added by decomposing them into their component
atomic objects and data, but I can't find where this happens, and
I don't find any mention of adding models in the documentation.
I have a model that produces a surface. To use the function
that produces the surface with XObjView, for example, I do
this:
IDL> XObjView, SurfModel()
To load the surface data into an iSurface object programmatically,
I have to extract the IDLgrSurface object from the model (it is the
first object in the model container), get the data out of this,
and add the data to the Data Manager like this.
surfModel = SurfModel() ; Get the model.
iSurface ; Start an iTool.
oSys = _IDLitSys_GetSystem() ; Obtain the iTool system.
oTool = oSys->_GetCurrentTool() ; Get the current tool.
surfObj = surfModel ->Get(/All) ; Extract IDLgrSurface from model.
surfObj[0] -> GetProperty, Data=thedata ; Extract the actual data.
objData = OBJ_NEW('IDLitData', Reform(theData[0,*,*]), $
IDENTIFIER='SURFMODELDATA, $
NAME='SURFDATA', TYPE='IDL2DArray')
oTool -> AddByIdentifier, '/Data Manager', objData
Now I can use the "SURFDATA" in a visualization in the iSurface tool,
or in any tool that can process data of type IDL2DARRAY.
Cheers,
David
