In this paper, we present a representation for three‐dimensional geometric animation sequences. Different from standard key‐frame techniques, this approach is based on the determination of principal animation components and decouples the animation from the underlying geometry. The new representation supports progressive animation compression with spatial, as well as temporal, level‐of‐detail and high compression ratios. The distinction of animation and geometry allows for mapping animations onto other objects.
