   abstract = {Editing 3D models is often performed on triangular meshes. We generalize
               editing operations based on differential coordinates to
               work on point clouds without explicit connectivity information.
               This allows a point cloud to be interpreted as a surface or 
               volumetric body upon which physically plausible deformations can be applied.
               Our multiresolution approach allows for a real-time editing experience
               of large point clouds with 1M points without any offline processing.
               We tested our method on a range of synthetic and real world data sets
               acquired by laser scanner. All of them were interactively editable
               and produced intuitive deformation results within few minutes of editing.},
