Perhaps you'd get some mileage out of the Image Border And Shadow [can be found @ /System/Library/Graphics/Quartz Composer Patches/Image Border And Shadow.qtz.
I wonder if that couldn't be further adapted to suit a 3D object, rather than merely exploiting it to add shadow to a 3d objects image input?
I guess what you are really looking for is a drop shadow, that you can spotlight within a Lighting patch?
I like what happens with the Custom patch, but really , when its taken out of the workflow, then you can really start having some fun with transparent imagery and parametric shapes and the use of the plane provides a shadow base that proves that the image / 3d object is really casting its own shadow. I've posted both 'solutions', so you can compare and contrast.
Have fun.
Betcha someone's gonna come up with one way better than mine :-)
tnx so much cybero and jersmy.
both example to me are important.
i'll try to figure out with something .
in the meantime i tried to obtain a shadow doing in a fake way.
i duplicated the object without colors , i tried to obtain a fake shadow but it's not really perfect(shadow do not coincide with ligth at the top of the object, but it seems that the render is really fluid. instead jersmy example is a lil bit slow but very very cool...

In your comp you could use the shadows in the lighting patch. See attached.
nice example, jersmi
thanks cybero. as usual your examples creatively push boundaries. i appreciate neurox's comp -- clear example of the 3D noise patch looking good.
