Dissertation/Thesis Abstract

Interactive control of deformable-object animations with intuitive motion pattern adherence
by Transue, Shane Michael, M.S., University of Colorado at Denver, 2014, 148; 1556899
Abstract (Summary)

Recent advances in the control of physically simulated objects have provided precise methodologies for deriving a desired physical state of a deformable object; however most of these approaches have severely limited the interactive component from real-time animation modification. To increase the level of interactivity in the generation of physically-based animations, we present an adaptive and intuitive methodology for controlling the localized deformation of physically simulated objects using an intuitive motion-based control interface. We achieve this control through the dynamic recording of physically simulated deformable objects and the development of high-level motion controls that provide effective manipulation techniques for altering the animation of deformable objects. To maximize the interactive component presented in this approach we consolidate existing feedback mechanisms in deformable-body control techniques to provide an intuitive simulation editing environment. We introduce the notion of control metaphors as the abstract formulations of primitive motions enacted by deformable-bodies when external forces modify the physical state of the object. As an application of this proposed control methodology we develop a practical solution for interjecting local deformations into dynamically recorded deformable objects. The effectiveness of this approach is demonstrated through interactively generated compound movements that introduce complex local deformations of the objects in existing physically-based animations. Additionally we validate the resulting movements imposed by the control metaphors by using directed behavior demonstrations through physical animations.
