Abstract:

A new technique is described for fitting scattered point cloud data. The fitting surface is determined as zero level isosurface of a tri
variate mode which is an implicit least squares fit of the data based upon radial basis functions. According to our numerical experiments, the new method is essentially faster than interpolating surface method based upon radial basis functions, and much simpler to implement.
