libigl

libigl is the mesh processing library of the Interactive Geometry Lab from ETH Zürich.

Its design principle are

• header-only
• the use of Eigen matrices to store everything, no complex data types
• minimal dependencies
• each function has a dedicated .h/.cpp pair of the same name

Mesh representation

to complete their documentation.

V : vertices - a nb_vertices by 3 matrix of double

Each row i represent a vertex with its $x$, $y$ and $z$ coordinates. i $\in$ [0,nb_vertices-1]
