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.
