We propose a controllable geometric flow that decomposes the interior volume of a triangular mesh into a collection of encapsulating layers, which we denote by a generalized foliation. For star-like genus zero surfaces we show that our formulation leads to a foliation of the volume with leaves that are closed genus zero surfaces, where the inner most leaves are spherical. Our method is based on the three-dimensional Hele-Shaw free-surface injection flow, which is applied to a conformally inverted domain. Every time iteration of the flow leads to a new free surface, which, after inversion, forms a foliation leaf of the input domain. Our approach is simple to implement, and versatile, as different foliations can be generated by modifying the injection point of the flow. We demonstrate the applicability of our method on a variety of shapes, including high-genus surfaces and collections of semantically similar shapes.
