angels-demons-priestAngels and Demons opened this weekend, and of course one of the major components of the movie is the plethora of classical roman cathedrals and churches.  However, the Vatican would not permit film crews inside for shooting, so the folks at CIS had to virtually create the environments for greenscreen work later.  However, they wouldn’t even allow them inside for proper shooting, so they entered as tourists and gathered as many photos as possible, with other tourists included.

To get around that, CIS created a giant virtual jigsaw puzzle in their studios, pulling together fragments from the images they shot. In order for the computer to be able to render a reasonable facsimile, they used multiple frames of every object taken from as many angles as possible. Then the special-effects artists at CIS worked on enhancing the images, which would ultimately be used with green-screen technology to create the interior of the churches.
