But in libigl It seems like you have specify to faces and direction vectors to design a field.\r\n\r\nUnfortunately I dont understand what that direction vector means or what coordinate space the vector it is in.

To specify the directions, the vectors should be in global coordinates, you can take a look here for a basic example that fixes only one face: http://libigl.github.io/libigl/tutorial/tutorial.html#505"}}
