How do I gain access to the idlitvissurface object underlying a "New Graphics" surface object (created using the surface() function)?
I need to programmatically set the scale_vertex_color array, which I cannot seemto do with the surface objref but can with the idlitvissurface objref like so: "my_idlitvissurface->setproperty, scale_vertex_color=[...]"
Thanks in advance,
Lance

Finally figured out how to do this. After you've instantiated your NG surface object (and assuming it's the only one), you can set the scale_vertex_color property this way:
igetproperty, 'surface', scale_vertex_color=svc
svc[3] = clip
isetproperty, 'surface', scale_vertex_color=svc
The first arg to i(g|s)etproperty is a path-like string that qualifies the itools visualization object. If 'surface' isn't unique enough, I believe you can use igetid() somehow immediately after instantiating the NG surface to get the fully qualified string (looks something like: "/TOOLS/GRAPHIC/WINDOW/VIEW_1/VISUALIZATION LAYER/DATA SPACE/SURFACE").
Hope this helps someone else...

Here's another way to do it:
oSystem = _IDLitSys_GetSystem()
oVis = oSystem->IDLitContainer::GetByIdentifier(igetid('surface'))
ovis->getproperty, scale_vertex_color=svc
svc[3] = clip
ovis->setproperty, scale_vertex_color=svc
