It is hard to know what you mean by "render", but here is
how I would render a 3D object (an MRI scan of the head)
with a white background in IDL:

!P.Background = !D.N_Colors
LoadCT, 0
head = GetImage('head.dat. XSize=80, YSize=100, Frame=57)
Scale3, XRange=[0,80], YRange=[0,100], ZRange=[0,57]
Shade_Volume, head, 50, vertices, polygons, /Low
TV, PolyShade(vertices, polygons, /T3D)
!P.Background = 0

Cheers,

David
