If you can render the objects separately, you can get a silhouette by 
rendering the object with finish{ambient 0 diffuse 0} against a white 
background. Or, render with +q0, a black pigment and a white background.
If you want a white object against a black background, then, you can use 
this:
pigment{rgb 1}finish{emission 1}
Or, +q0, a white pigment and black background.

For both options, you don't need any light.

Then, in Inkscape, you can use that image to generate that outline. You 
may also use a contour filter as another way to get a line around the 
object.

Only work for the object seen from a specific direction.
