a) In terms of folding sequences, many crease lines are often part of the same
fold.
Is et meaningful to represent this, or is it better to let the program compute
that?
b) The assignment of Mountain, Valley, and Neutral, would that be part of the
input?
(Neutral are unfolded crease lines, “unused” in the model, but either an
artefact of the folding sequence or intentionally introduced for their
decorative effects).
c) Having neutral creases, non-planar graphs become possible, since a neutral
line may cross other lines in points which will not be a vertex of the final
model.
Or is it better to represent them explicitly, and then derive the property that
it does not affect the other crease’s position in the final model?
