LibGP is a head-only C++ library for geometry processing, which was developed during my early Ph.D. carreer.
LibGP supports my first two papers on geometry processing, including Rolling Guidance Normal Filter in SIGGRAPH Asia 2015 and Mesh Denoising via Cascaded Normal Regression in SIGGRAPH Asia 2016.
The code is released under the MIT license. Feel free to use is and hope it may also be useful for you.
