While at Disney, I helped develop software for the 2010 stereoscopic release of Beauty and the Beast. Among the tools I wrote were python scripts which procedurally generated shake graphs from the original scanned cells, in part by querying a CAPS database.
Another notable contribution I authored was a “depth visualiser”, which enabled artists to monitor stereoscopic depth. The artist’s process for this film was to generate animated greyscale depth maps using a variety of compositing techniques, with luminance determining the stereoscopic depth.
With the “depth visualiser”, artists operated a slider (in shake) to draw an outline indicating the depth of shot elements when gradients were difficult to perceive, not unlike a 3d image plane.
The following Siggraph papers outline the processes and technology developed for this release.
