is it possible to restructured an upright object from its shadow only, for example an cube or any model?

[Vanadium 50]

Can you tell the difference between the shadow of a disk and that of a sphere?

[rajeshmarndi]

No.
If the light source is not on top of the model, the shadow will be different.
But i understand any vertices that is hidden between the object and the shadow will not be revealed.

[rajeshmarndi]

if the object is an transparent like an glass cube where we can see its edges on its shadow????
and again if the light source is not from top and from different angle.
