  text: 'We introduce dynamically warping grids for adaptive liquid simulation. Our
    primary contributions are a strategy for dynamically deforming regular grids over
    the course of a simulation and a method for efficiently utilizing these deforming
    grids for liquid simulation. Prior work has shown that unstructured grids are
    very effective for adaptive fluid simulations. However, unstructured grids often
    lead to complicated implementations and a poor cache hit rate due to inconsistent
    memory access. Regular grids, on the other hand, provide a fast, fixed memory
    access pattern and straightforward implementation. Our method combines the advantages
    of both: we leverage the simplicity of regular grids while still achieving practical
    and controllable spatial adaptivity. We demonstrate that our method enables adaptive
    simulations that are fast, flexible, and robust to null-space issues. At the same
    time, our method is simple to implement and takes advantage of existing highly-tuned
    algorithms.'
