We present a new algorithm for improving an available
(conservative) estimate of the shape of an object using constraints
from ray-tracing. In particular, we exploit incoherences
between the lit portions of the object - detected on
a set of acquired images - and the shadows that the current
estimate casts on itself. Whenever a contradiction is
found the current estimate is modified in order to remove
the inconsistency. Sufficient conditions for the correctness
of the algorithm and a discussion of their validity are provided.
Finally, we describe a simple implementation of the
method and present some preliminary experimental results
from computer simulations.
