Here is a list of all documented files with brief descriptions:

[detail level 1234]

include
Curvature
include
Curvature.h	This file looks at option to compare two curves based on the curvatures of their vertices. It is based on the paper: K. Crane, U. Pinkall, and P. Schroeder, "Robust fairing via conformal curvature flow", ACM Transactions on Graphics, Vol. 32, No. 4 (2013), and on the code SpinXform_OpenGL from Keenan Crane (available at: https://www.cs.cmu.edu/~kmcrane/index.html#code)
