faces_vertices and faces_edges should align in start so that faces_edges[f][i] is the edge connecting faces_vertices[f][i] and faces_vertices[f][(i+1)%d] where d is the degree of face f.
The diagonal-cp and diagonal-folded examples violate this rule; these are the only examples which contain faces_edges. They say they were created with Crease Pattern Editor, so maybe this is a bug in that tool?
From the spec:
faces_vertices
andfaces_edges
should align in start so thatfaces_edges[f][i]
is the edge connectingfaces_vertices[f][i]
andfaces_vertices[f][(i+1)%d]
whered
is the degree of facef
.The diagonal-cp and diagonal-folded examples violate this rule; these are the only examples which contain
