artists can freely pose the
shape while modeling to adjust it, or to examine the motion
of the model by using poses as key-frames. Furthermore,
the unification removes friction from incremental and iterative
character modeling and animation (Fig. 1). Our algorithms are
efficient and execute in real-time, far below the one second delay
that interrupts mental flow [Nielsen 1993]. Our work builds
on Pinocchio [Baran and Popovic 2007], adapting its skin weight ´
algorithm to support incremental merging and cutting of shapes,
and revisits the Chordal Axis Transform [Prasad 1997] used by
Teddy [Igarashi et al. 1999] for skeleton generation. Specifically,
our contributions are:
