  text: We present a method for recovering a temporally coherent, deforming triangle
    mesh with arbitrarily changing topology from an incoherent sequence of static
    closed surfaces. We solve this problem using the surface geometry alone, without
    any prior information like surface templates or velocity fields. Our system combines
    a proven strategy for triangle mesh improvement, a robust multi-resolution non-rigid
    registration routine, and a reliable technique for changing surface mesh topology.
    We also introduce a novel topological constraint enforcement algorithm to ensure
    that the output and input always have similar topology. We apply our technique
    to a series of diverse input data from video reconstructions, physics simulations,
    and artistic morphs. The structured output of our algorithm allows us to efficiently
    track information like colors and displacement maps, recover velocity information,
    and solve PDEs on the mesh as a post process.
