Interesting question. I've always wanted the light to shine on
everything...
You can control this by creating two separate views. Create identical
views, one for each lighting scenario, and set the transparent keyword
on one. Add your objects accordingly and place them in a viewgroup to
display.
Remember to order your views in your viewgroup such that the opaque view
is first (farthest away) followed by the transparent one(s).
o1 = obj_new('orb', COLOR=[100,200,255], POS=[-2,0,0])
o2 = obj_new('orb', COLOR=[255,200,100], POS=[2,0,0])
l1 = OBJ_NEW('IDLgrLight', TYPE=1, INTENSITY=1.0)
view1 = OBJ_NEW('IDLgrView', VIEWPLANE_RECT=[-3,-3,6,6])
view2 = OBJ_NEW('IDLgrView', VIEWPLANE_RECT=[-3,-3,6,6], $
/TRANSPARENT)
viewgroup = OBJ_NEW('IDLgrViewgroup')
m1 = OBJ_NEW('IDLgrModel')
m2 = OBJ_NEW('IDLgrModel')
m2->Add, [o2]
m1->Add, [o1,l1]
view1->Add, m1
view2->Add, m2
viewgroup->Add, [view1,view2]
window=OBJ_NEW('idlgrwindow')
window->Draw, viewgroup
