Title:
Simulation of Leaping, Tumbling, Landing, and Balancing Humans

Abstract:
This thesis describes an approach for generating transitions between
simulated human behaviors in which the designer concentrates effort on
the creation of parameterized basis behaviors that can be combined
together in an automatic fashion. The parameterization allows the
generation of a wide variety of motions from a single basis behavior.
If the behaviors are well designed, the exit states of one leaves the
simulated character in a valid initial state for the next. This nesting
of the input and output states allows easy transitions between behaviors
and the generation of many complex behaviors from a small set of basis
behaviors. I demonstrate this approach with four basis behaviors:
leaping, tumbling, landing, and balancing. Each parameterized control
system allows the user to specify properties of the desired behavior
such as how high or far to jump and the number of somersaults to
perform. I demonstrate transitions between the basis controllers by
generating a diverse set of behaviors, including a standing broad jump,
vertical leap, forward somersault, backward somersault, back handspring,
and various platform dives.
