While 3D enhancement creates an entirely updated look, with its own revolutionary technological aspects, the original animation for "Beauty and the Beast" was also quite groundbreaking. This was only Disney's second film to employ its in-house Computer Animation Production System (CAPS), which, among other highly advanced concepts, went beyond normal animation to allow for the use of CGI. The technology was developed with help from Pixar, and it wouldn't be the last time the two companies worked together. Perhaps nowhere is the technology of CAPS more prominent than in the ballroom-dance sequence, where Belle and the Beast waltz their fannies off. The camera appears to be moving around them as a computer-generated background bursts to life behind them. According to CGI artistic supervisor Jim Hillin, "The ballroom sequence features the first computer-generated color background to be both animated and fully dimensional."
