WebBackward warping/skinning has been used to model non-rigid implicit shapes. It maps poitns from deformed space to canonical space. The backward skinning weights field is defined in deformed space, therefore it's pose-dependent and does not generalize to unseen poses. We propose to use Forward skinning for animating implicit shapes.
