After watching the emotion wrenching "Life Of Pi" i was amazed at the visual feasts and brilliant graphics, it was because of the high quality graphics that i couldnt be sure if the tiger was real or not?
“We used [real tigers] for single shots, where it was just the tiger in the frame, and they’re doing something that didn’t have to be all that specific in the action that we were after,” Westenhofer told The New York Times. “By doing that, it set our bar high for CGI. We couldn’t cheat at all. It pushed the artists to go and deliver something that’s never been done before, something as photo-real as anyone has ever done with an animal.”
