History of FOLD Specifications
Version 1 = 1.0
Version 1.1
- Rename
edges_foldAngles → edges_foldAngle and
edges_lengths → edges_length
for consistent pluralization with the rest of the spec.
Version 1.2
- Add join edge (
"J") option to edges_assignment.
- Add cut/slit edge (
"C") option to edges_assignment (optional).
- Add
joins/noJoins and cuts/noCuts to frame_attributes.
- Add
convexFaces/nonconvexFaces to frame_attributes.
- Define
vertices_edges and faces_faces.
- Extend definition of
vertices_faces, edges_faces, and faces_faces
to allow null values, allowing for consistent ordering of all arrays and
consistent orientation.
- Specify correspondence between “faces” and “material”, to clarify that the
exterior (unbounded) face of a planar graph is not typically a face.
- Clarify that support for multiple frames is optional.
