solver progresses, mass accumulates inside the surface. Right: The result of an implicit function reconstruction from the flow solution.
Abstract
We introduce a volumetric space-time technique for the reconstruc-
tion of moving and deforming objects from point data. The output
of our method is a four-dimensional space-time solid, made up of
spatial slices, each of which is a three-dimensional solid bounded
by a watertight manifold. The motion of the object is described
