--INFORMATION

The Tin Refinement algorithm is from my collaborator Yitong Xia(xiayitong0630@gmail.com), and her repository:

https://github.com/YitongXia/ground-filtering.

Thank her for her efforts and dedication.

CSF algorithm is based on the cloth simulation with verlet integration.

The idea of CSF is from this paper : http://www.mdpi.com/2072-4292/8/6/501/htm

The basic architectures and ideas are inspired by this article (its related code is open source).

--HOW TO USE

It's a cmake project, in principle, it can run on all platforms if everything goes fine. Use the source code to build the project and run it.
