Vista - Outerglow on 3D objects

I'm searching for a solution to create some outerglow effect on a 3D obejct.
I have seen this in some of wpf demos. ModelVisual3D doesn't have
BitmapEffect property like other visuals. Perhaps any one of you knows some
tricks how to achieve this?

Thanks for all suggestions!

For WPF 3D V1 you are not at a DX 9 level...no access to pixel shaders like
XNA. Therefore, older game techniques have to be used to create the effects.
Generally, this means adding some geometries and using emissive materials
and\or preprocessing your images via photoshop and\or baking in a 3D software
tool like MAX.

For example, if you want a glow around the earth, put a plane through a
shere, put your glow image on the plane - you can also use emmissive and
other techniques. Of course, if the camera moves, the glow plane has to move,
and now you need code to billboard the plane.
