  text: This paper presents a method for computing topology changes for triangle meshes
    in an interactive geometric modeling environment. Most triangle meshes in practice
    do not exhibit desirable geometric properties, so we develop a solution that is
    independent of standard assumptions and robust to geometric errors. Specifically,
    we provide the first method for topology change applicable to arbitrary non-solid,
    non-manifold, non-closed, self-intersecting surfaces. We prove that this new method
    for topology change produces the expected conventional results when applied to
    solid (closed, manifold, non-self-intersecting) surfaces---that is, we prove a
    backwards-compatibility property relative to prior work. Beyond solid surfaces,
    we present empirical evidence that our method remains tolerant to a variety of
    surface aberrations through the incorporation of a novel error correction scheme.
    Finally, we demonstrate how topology change applied to non-solid objects enables
    wholly new and useful behaviors.
