Handout said we're deal with pure quad mesh. What assumption can we made on pure quad mesh? I thought in that case each vertex can only have 4 neighbour faces and vertices, but it's not. Also from visualization, there are triangular meshes... And we can see there is one vertex has 5 neighbour vertices...

I am also wondering about this. I just finished implementing my function with the pure quad mesh assumption and it falls apart around the areas with the awkward face connections (mainly around the seams splitting the model in two down the middle). Any thoughts on how to work around this? Which assumptions can we make?
