This fall marks a milestone in animation history as Chris Wedge, one of the founders of Blue Sky Studios Inc., releases his latest short film "Bunny." The seven-minute piece is the first computer-animated film to use radiosity, an advanced computer rendering technique that mimics the most subtle properties of natural light. Written and directed by Wedge, produced by Nina Rappaport, with music by singer/songwriter Tom Waits, "Bunny" has already been invited to show at IMAGINA in Monaco and The Film Forum in New York. It also screened at Laemmle Theaters in Los Angeles, qualifying it for 1998 Academy Award consideration.
Wedge has always encouraged his crew to think like cinematographers and that philosophy is evident in the sometimes dark, film-noirish "Bunny" which sets a new standard of mood and cinematic storytelling in computer animation.
"It's a suspense story. A case of mistaken identity, with a twist that I think has a lot of heart to it," said Wedge. When asked why a rabbit? Wedge answered, "I was always doodling rabbits, I think because I was fascinated by the character of Uncle Wiggly and the animation in those old illustrations from the 1930's. That was definitely an influence. I wanted to create something in that rich storybook style - realistic, yet fantasy."
In fact, the short, which began as an effort to stretch the limits of Blue Sky Studios' proprietary lighting software, has such a warm, filmic, photorealistic style that it belies the computer technology that made it possible. Through the use of a software technique called radiosity, which is a complete simulation of how natural light works, Wedge and his crew were able to create an unparalleled dimensionality and organic realism never before attempted in a computer-animated film.
"In a real environment there is usually more than one single color of light illuminating a scene," Wedge explained. "There are all these sympathetic hues - yellow bouncing off a yellow wall, greens being reflected from trees outside, blue from the sky; colors we may not even be aware of unless they're missing. Recreating that ambient illumination in the computer gives us the richness of live action photography and the versatility to make anything happen."
Walvoord said the team couldn't tweak the lighting to correct the brightness of the stove because with radiosity, that little change affected the whole global lighting structure. Ironically, this problem is exactly what happens on a live-action set. "In the studios, they're always fighting radiosity, " Walvoord said, smiling, "But they can stick out their hands and figure out where the shadow is coming from - It's a little more complicated in the computer." The team ended up putting the computer-equivalent of 'bounce cards' and flags' in the programming, blocks that would add or take away indirect light. "And sometimes, we just had to throw physics out the window and do what looked right," Walvoord stated.
Bafaro, who with Dooley was responsible for the majority of the scenes in the film, said she was especially sensitive to the characters' physical presence, adding "with the moth, the focus was on the giving weight to the body, almost as if it is a struggle for him to stay airborne. Bunny was this crotchety, bitter, old woman character, so her movements had to be feeble and full of effort but with quick expressive rabbit ears and body movements. "
Jim Bresnahan, who also animated for the film, said getting physical substance to read on screen has a lot to do with timing and physics. "A good animator has to be a bit of a scientist as well as an actor," Bresnahan explained, adding "what's unique about "Bunny" and Blue Sky animation in general, is an attention to character development. We aren't just out there moving limbs up and down like puppeteers. We try to understand the character's history and motivation. It is that aspect of a real performance that gives our work a lot of heart and believability."
"The key to Bunny," Wedge concludes, "is that it is a film experience and a story first." "We just happened to go insane with the technology, but it's designed to hide that fact, so there are no plastic surfaces; nothing that has a defined computer signature and no particularly graphic special effects. We don't want people to think too hard about what went into creating it. We just want them to sit back and enjoy it."
