Which brings us to Rhinoceros CG director/digital artist Arman Matin, who must've been a radiologist in a previous life. Since the clothing can't disappear in this X-ray, "we knew we needed to integrate CG with existing live-action footage," explains Matin. "It's the layering of tons of different elements that makes this X-ray style unique. You see the clothing, under the clothing, the objects under the clothing, as well as the skeleton." The shoot itself was a one-day affair, but the animation took six weeks. The painstaking detail started on set, where the actors were photographed against a measured grid so the Rhino artists could build an appropriate skeleton for each of them. All small objects on the set - chairs, silverware, briefcases, everything - got the same treatment, with all of it later modeled in Maya to replace the live-action objects. "Some shots required moving cameras, for which we placed markers and used Maya to track the camera information," says Matin. "For some shots, we even had to film subjects against greenscreen and composite them into the plate later." The blackplates were cleaned up in Inferno, eliminating markers and unwanted objects, then everything had to be positioned in CGI to match the live action and composited in Adobe AfterEffects. "Every time an actor moved, we had to animate their skeletons to move right along with them," adds Matin. "It was literally a frame-by-frame process." After animators added layers of clothing to the skeletons, an X-ray shader, developed in Maya, was employed to render it all in X-ray tonalities. After the final images were color corrected, the transition from live to X-ray effect took place in Inferno.
"It's the orchestration of the balance of CG and live action that makes it work, says Miller. "Each shot is anywhere from 30 to 60 layers thick with CG and live action."
"We had to carefully control the transparency of each layer and decide how much to fade out so the viewer will know what's going on," continues Matin. "Otherwise you'd be totally confused by the amount of information you're seeing."
Does this technique have a pet name? "On the floor at Rhinoceros, it's referred to as Armandovision," laughs Miller.
