Geometric data is now ubiquitous. Such 3D content is either acquired using LiDAR scans, MRI scans, etc., or created using 3D modelers, or obtained as output of simulation processes. The data, however, come in low-level representations (e.g., points, polygons, voxel grids) and begets little understanding of the underlying objects or processes. This is unfortunate since such data have significant re ...
