Query: Reverse Engineering Point Clouds to Fit Tensor Product B-Spline Surfaces
  by Blending Local Fits   Being able to reverse engineer from point cloud data to obtain 3D models is
important in modeling. As our main contribution, we present a new method to
obtain a tensor product B-spline representation from point cloud data by
fitting surfaces to appropriately segmented data. By blending multiple local
fits our method is more efficient than existing techniques, with the ability to
deal with more detail by efficiently introducing a high number of knots.
Further point cloud data obtained by digitizing 3D data, typically presents
many associated complications like noise and missing data. As our second
contribution, we propose an end-to-end framework for smoothing, hole filling,
parameterization, knot selection and B-spline fitting that addresses these
issues, works robustly with large irregularly shaped data containing holes and
is straightforward to implement.
