libigl - A C++ Geometry Processing Library

A simple C++ geometry processing library with wide functionality, including construction of sparse discrete differential geometry operators and finite-elements matrices such as the contangent Laplacian and diagonalized mass matrix, simple facet and edge-based topology data structures, mesh-viewing utilities for OpenGL and GLSL, and many core functions for matrix manipulation which make Eigen feel a lot more like MATLAB

Github / Tutorial

What I like about it:

header-only library, but supports external high-performance libraries
Uses Eigen for matrices and linear algebra (another header-only library)
Has a ton of useful, self-contained, and best of all, working tutorials!

In my experience, 99% of the effort in setting up the tutorials was performed by git and cmake. But compilation time takes a while (sometimes a drawback of header-only libraries), so I'll go through the setup process, but then I'll run demos from a precompiled version.

Tutorials to try:

106_ViewerMenu
201_Normals
202_GaussianCurvature
205_Laplacian
405_AsRigidAsPossible
605_Tetgen
707_SweptVolume
Taking requests!

What you need (Windows):

Git
CMake
Visual Studio 2017 Community (2015 should also work, but 64-bit is a must either way!)
