You need to do something like this

idAnnotate = itool_obj -> FindIdentifiers('*/ANNOTATION LAYER') ;Get annotation layer ID
oAnnotate = itool_obj -> getByIdentifier(idAnnotate) ;Get annotation object
oAnnotate -> add, OBJ_NEW('IDLitVisText', _STRING = 'This is a string', $ ;Add title in annotation plane
ALIGNMENT = 0.5, $
VERTICAL_ALIGNMENT = 1.0, $
FONT_SIZE = 24, $
LOCATION = [0.5, 0.5, 0.5])

Also, search the IDL docs for the string "onglass" for more on 3-D and
"on-the-glass text
