 In addition , CAPS allowed easier combination of hand @-@ drawn art with computer @-@ generated imagery , which before had to be plotted to animation paper and then xeroxed and painted traditionally . This technique was put to significant use during the " Beauty and the Beast " waltz sequence , in which Belle and Beast dance through a computer @-@ generated ballroom as the camera dollies around them in simulated 3D space . The filmmakers had originally decided against the use of computers in favor of traditional animation , but later , when the technology had improved , decided it could be used for the one scene in the ballroom . The success of the ballroom sequence helped convince studio executives to further invest in computer animation .
