Computer puppetry: An importance-based approach
Hyun Joon Shin, Jehee Lee, Sung Yong Shin, Michael Gleicher
Pages: 67-94
DOI: 10.1145/502122.502123
Computer puppetry maps the movements of a performer to an animated character in real-time. In this article, we provide a comprehensive solution to the problem of transferring the observations of the motion capture sensors to an animated character...

Spherical averages and applications to spherical splines and interpolation
Samuel R. Buss, Jay P. Fillmore
Pages: 95-126
DOI: 10.1145/502122.502124
This article introduces a method for computing weighted averages on spheres based on least squares minimization that respects spherical distance. We prove existence and uniqueness properties of the weighted averages, and give fast iterative...
