clay animation meaning in Information Science terminology / glossary / dictionary is:
Stop-motion filmanimation in which the subjects are modeled in a malleable substance, such as plasticine or silicone rubber, usually against a background which may also be deformable (see this example). For each frame, the position of at least one of the subjects is altered incrementally, creating the illusion of continuous movement when the footage is played back at the usual 24 frames per second. Clay animation is very labor-intensive because twelve changes are generally required for each second of film. Synonymous with claymation.
