with the viewing angle. Further, image matching has been used
for model and registration refinement (Debevec et al., 1996; see
also Bernardini et al., 2001); indeed, a multiple image coverage
and precise starting values supplied by the 3D model may allow
to refine the model and/or the textured output. The above points
indicate possible future tasks of the work presented here.
