  text: We present a method for smoothly blending between existing liquid animations.
    We introduce a semi-automatic method for matching two existing liquid animations,
    which we use to create new fluid motion that plausibly interpolates the input.
    Our contributions include a new space-time non-rigid iterative closest point algorithm
    that incorporates user guidance, a subsampling technique for efficient registration
    of meshes with millions of vertices, and a fast surface extraction algorithm that
    produces 3D triangle meshes from a 4D space-time surface. Our technique can be
    used to instantly create hundreds of new simulations, or to interactively explore
    complex parameter spaces. Our method is guaranteed to produce output that does
    not deviate from the input animations, and it generalizes to multiple dimensions.
    Because our method runs at interactive rates after the initial precomputation
    step, it has potential applications in games and training simulations.
