{A}pproximate {U}nfolding},
abstract = {We propose a new method for producing unfolded papercraft patterns
of rounded toy animal figures from triangulated meshes by means of
stripbased approximation. Although in principle a triangulated
model can be unfolded simply by retaining as much as possible of
its connectivity while checking for intersecting triangles in the
unfolded plane, creating a pattern with tens of thousands of
triangles is unrealistic. Our approach is to approximate the mesh
model by a set of continuous triangle strips with no internal
vertices. Initially, we subdivide our mesh into parts
corresponding to the features of the model. We segment each part
into zonal regions, grouping triangles which are similar
topological distances from the part boundary. We generate triangle
strips by simplifying the mesh while retaining the borders of the
zonal regions and additional cutlines. The pattern is then
created simply by unfolding the set of strips. The distinguishing
feature of our method is that we approximate a mesh model by a set
of continuous strips, not by other ruled surfaces such as parts of
cones or cylinders. Thus, the approximated unfolded pattern can be
generated using only mesh operations and a simple unfolding
algorithm. Furthermore, a set of strips can be crafted just by
bending the paper (without breaking edges) and can represent
smooth features of the original mesh models.},
