Abstract

We present a method to produce smooth transitions between arbitrary pieces of character animation, which is based on the application of dynamic transition curves. Unlike other approaches, we achieve anytime interruptibility for body ex- pressions, that is, gestures can be changed anytime during execution while maintaining naturalness of motion transi- tion. To obtain highly natural skeletal movement, our ap- proach is integrated with motion parametrization, as pro- posed in theVerbs and Adverbs" technique [18], and further methods of fuzzy motion blending. We will demonstrate how the latest version of the Multimodal Presentation Markup Language (MPML3D) integrates parameterized agent be- havior, and can support the incorporation of personality and emotional attentiveness in a straightforward way.
