We present an approach to define shape deformations by constructing and
interactively modifying C1 continuous time-dependent divergence-free vector
fields. The deformation is obtained by a path line integration of the mesh
vertices. This way, the deformation is volume-preserving, free of (local and
global) self-intersections, feature preserving, smoothness preserving, and
local. Different modeling metaphors support the approach which is able to
modify the vector field on-the-fly according to the user input. The approach
works at interactive frame rates for moderate mesh sizes, and the numerical
integration preserves the volume with a high accuracy.
