  Time-varying connectivity of triangle mesh sequences leads to substantial
difficulties in their processing. Unlike editing sequences with constant
connectivity, editing sequences with varying connectivity requires addressing
the problem of temporal correspondence between the frames of the sequence. We
present a method for time-consistent editing of triangle mesh sequences with
varying connectivity using sparse temporal correspondence, which can be
obtained using existing methods. Our method includes a deformation model based
on the usage of the sparse temporal correspondence, which is suitable for the
temporal propagation of user-specified deformations of the edited surface with
respect to the shape and true topology of the surface while preserving the
individual connectivity of each frame. Since there is no other method capable
of comparable types of editing on time-varying meshes, we compare our method
and the proposed deformation model with a baseline approach and demonstrate the
benefits of our framework.
