Abstract: We present a new framework for interactive shape deformation modeling and key frame interpolation based on a
meshless finite element formulation. Starting from a coarse nodal sampling of an object’s volume, we formulate
rigidity and volume preservation constraints that are enforced to yield realistic shape deformations at interactive
frame rates. Additionally, by specifying key frame poses of the deforming shape and optimizing the nodal dis-
placements while targeting smooth interpolated motion, our algorithm extends to a motion planning framework
for deformable objects. This allows reconstructing smooth and plausible deformable shape trajectories in the
presence of possibly moving obstacles. The presented results illustrate that our framework can handle complex
shapes at interactive rates and hence is a valuable tool for animators to realistically and efficiently model and
interpolate deforming 3D shapes.
