Surface flatten, Mass-spring model, Strain energy, and
3D surface flattening is a hot research theme in the
field of computer aided design and manufacture. A
numerical simulation method for surface flattening is
proposed in this paper. First of all, a 3D surface is
flattened to a 2D pattern by Geodesic curvature method.
Then an accurate 2D pattern is created through building
up the mass-spring model and carrying out the interactive
operation. On the other hand, it can reduce the strain
energy and improve the accuracy of 2D pattern
appearance by way of trimmed surface. Finally, several
examples of developable and non-developable surfaces
are simulated in order to prove the feasibility of the
method in this paper.
