We describe a variety of curvature estimation methods and a procedure to evaluate the accuracy and stability of these methods in a paper accepted to the CAGD Special Issue on Geometric Mesh Processing.
The source code for the curvature calculation routines and the Curvature Case Study project is in a zip file along with libraries and Visual C++ 6.0 project files. The source code is also available from Sourceforge.
The format for the raw curvature data from the Curvature Case Study runs is described in the README file.
