I've just updated the documentation for the Tinfour open-source Java project. Tinfour supports the creation of triangular mesh structures from unstructured data sets (collections of randomly-positioned data points). The focus of the project is the Delaunay triangulation. And while that topic is a bit specialized, I believe that there is enough general material in the documentation that visitors here at the Coderanch may find it interesting (and maybe even useful).
In particular, I've updated notes on Natural Neighbor Interpolation which is a technique for creating smooth surfaces from unstructured data such as elevation surveys, weather observations, etc. I've also posted new material describing the algorithms used by the interpolator (see A Fast and Accurate Algorithm for Natural Neighbor Interpolation)
Finally, I've received a lot of support from folks here at the Coderanch, and I'd like to thank you all for your many helpful suggestions and encouragement.
