Abstract

For real-time animation, keyframe animation that consists of translation, rotation, scaling interpolator nodes is used widely in 3D graphics. This paper presents 3D keyframe animation watermarking based on vertex coordinates in CoordIndex node and keyvalues in PositionInterpolator node for VRML animation. Experimental results verify that the proposed algorithm has the robustness against geometrical attacks and timeline attacks as well as the invisibility.
