We present an animation synthesis technique that produces high quality avatar animation from coarse or incomplete motion input by matching, in real-time, the input against thousands of high-quality pre-recorded motion capture templates. The technique uses subsequence multivariate Quaternion Dynamic Time Warping with the angle between quaternions as a distance measure. Our implementation of the technique using compute shaders shows performance gains orders of magnitude greater than the state-of-the-art DTW implementations.
