Computer Animation Production System

The Computer Animation Production System (CAPS) is a proprietary collection of software, scanning camera systems, servers, networked computer workstations, and custom desks developed by the Walt Disney Company together with Pixar during the late-1980s. Its purpose was to computerize the ink and paint and post-production processes of traditionally animated feature films produced by Walt Disney Animation Studios.
==CAPS in film production==
CAPS was the first digital ink and paint system used in animated feature films, designed to replace the expensive process of transferring animated drawings to cels using India ink or xerographic technology, and painting the reverse sides of the cels with gouache paint. Using the CAPS system, enclosed areas and lines could be easily colored in the digital computer environment using an unlimited palette. Transparent shading, blended colors, and other sophisticated techniques could be extensively used that were not previously available.
The completed digital cels were composited over scanned background paintings and camera or pan movements were programmed into a computer exposure sheet simulating the actions of old style animation cameras. Additionally, complex multiplane shots giving a sense of depth were possible. Unlike the analog multiplane camera, the CAPS multiplane cameras were not limited by artwork size. Extensive camera movements never before seen were incorporated into the films. The final version of the sequence was composited and recorded onto film. Since the animation elements exist digitally, it was easy to integrate other types of film and video elements, including three-dimensional computer animation.
==Evolution of the system==
The first usage of the CAPS process was Mickey standing on Epcot's Spaceship Earth for "The Magical World of Disney" titles. The system's first feature film use was in the production of The Little Mermaid in 1989; however, the use of the system was limited to the farewell rainbow sequence near the end. The rest of the film used traditional painted cels. Subsequent films were made completely using CAPS; the first of these, The Rescuers Down Under, was the first 100% digital feature film ever produced. Subsequent films, including Beauty and the Beast, Aladdin, The Lion King, and The Hunchback of Notre Dame took more advantage of CAPS' 2D/3D integration. The system has not been used since 2006's The Little Matchgirl.
==Special edition editing==
For the Special Edition IMAX and DVD versions of Beauty and the Beast, Aladdin, The Lion King, and Mulan, new renders of the original elements were done and recorded to alternate master formats. In addition, Beauty and the Beast and The Lion King had newly animated sequences added to their special editions, and both of the IMAX editions and Aladdin had significant cleanup/restoration done on the original digital sequence elements to enhance detail, correct mistakes, and solidify clean-up animation and drawing.
==Significance==
In 1992, the team that developed CAPS won an Academy of Motion Picture Arts and Sciences Scientific and Engineering Award. They were:
*Randy Cartwright (Disney)
*David B. Coons (Disney)
*Lem Davis (Disney)
*Thomas Hahn (Pixar)
*James Houston (Disney)
*Mark Kimball (Disney)
*Dylan W. Kohler (Disney)
*Peter Nye (Pixar)
*Michael Shantzis (Pixar)
*David F. Wolf (Disney)
*Walt Disney Feature Animation Department
CAPS was capable of a high level of image quality using significantly slower computer systems than are available today. The final frames were rendered at a 2K digital film resolution (2048 pixels across at a 1.66:1 aspect ratio), and the artwork was scanned so that it always held 100% resolution in the final output, no matter how complex the camera motion in the shot.
== Decline and eventual replacement ==
The Two Movies Treasure Planet (2002) and Home on the Range (2004) and Short The Little Matchgirl (2006). under-performed financially in their theatrical runs. This, combined with the success of CGI-animated feature films from Pixar Animation Studios and competitor DreamWorks Animation, eventually prompted Walt Disney Feature Animation's management team to close down their traditional 2D animation department in 2004. The CAPS desks were removed and the custom automated scanning cameras were dismantled and officially scrapped. By 2005, only one desk system remained, and that was only for reading the data for the films that had been made with CAPS
In 2007, John Lasseter became the studio's new head of management team and called for the 2D animation unit's reopening. Rather than return to CAPS, however, Disney's subsequent traditionally animated feature and short film production projects How to Hook Up Your Home Theater (2007), The Princess and the Frog (2009), The Ballad of Nessie (2011), and Winnie the Pooh (2011) were produced using Toon Boom Animation's Toon Boom Harmony commercial animation computer software, which offered a more up-to-date modern contemporary digital animation system.
