text: The generation of realistic motion satisfying user-defined requirements is
one of the most important goals of computer animation. Our aim in this paper is
the synthesis of realistic, controllable motion for lightweight natural objects
in a gaseous medium. We formulate this problem as a large-scale spacetime optimization
with user controls and fluid motion equations as constraints. We have devised
novel and effective methods to make this large optimization tractable. Initial
trajectories are generated with data-driven synthesis based on stylistic motion
planning. Smoothed particle hydrodynamics (SPH) is used during optimization to
produce fluid simulations at a reasonable computational cost, while interesting
vortex-based fluid motion is generated by recording the presence of vortices in
the initial trajectories and maintaining them through optimization. Object rotations
are refined as a postprocess to enhance the visual quality of the results. We
demonstrate our techniques on a number of animations involving single or multiple
objects.
