3D points to continuous surface

Sparse information are often the result of computer science task because we have found robust information for only a part of the dataset. But we want to reconstruct a credible result that can represent the best the sampled data in front of the real data.

Interpolation is a good way to fill holes. We all know method like Bezier, Lagrange, B-Splines, Nurbs methods. But other method exist and I want mention them here :





Surface reconstruction algorithm gives us a much better feel for the data. There are Kriging that perform this task, but Kriging can be slower on large data sets. I purpose you to read the master thesis of Mike Thiesen. A FAST LAYERED ALTERNATIVE TO KRIGING.
