This repository has been initialized as a copy of https://github.com/alecjacobson/nested_cages, but has been reconfigured to support the newer version of the libgl library, as well as the dependencies required for calls to the viewer to work. After cloning, please replace the following folders with their counterparts in the original version:
libigl/external/tetgen
libigl/include/igl/copyleft/cgal
