I made this error when using IGl.BBW.This is the code I used b, bc = boundary_conditions(V, F, C, P, BE, CE) bbw = igl.BBW(0, 2) print(dir(igl.BBW)) print("show", V, V.shape,F.shape,b.shape, bc.shape)...

Tutorial 3: missing data

All the example data for Tutorial 3 is not in the repository https://github.com/libigl/libigl-python-bindings/blob/40be4c4fa5b8b77d37128b944883656d809d2444/tutorial/tut-chapter3.ipynb
