SUMMARY:Shape Approximation by Developable Wrapping
DESCRIPTION:Technical Papers, Technical Papers Q&A\n\nShape Approximation
by Developable Wrapping\n\nIon, Rabinovich, Herholz, Sorkine-Hornung\n\nWe
present an automatic tool to approximate curved geometries with piecewise
developable surfaces. At the center of our work is an algorithm that wrap
s a given 3D input surface with multiple developable patches, each modeled
as a discrete orthogonal geodesic net. Our algorithm features a global op
timization routine for effectively finding the placement of the developabl
e patches. After wrapping the mesh, we use these patches and a non-linear
projection step to generate a surface that approximates the original input
, but is also amendable to simple and efficient fabrication techniques tha
nks to being piecewise developable. Our algorithm allows users to steer th
e tradeoff between approximation power and the number of developable patch
es used. We demonstrate the effectiveness of our approach on a range of 3D
shapes. Compared to previous approaches, our results exhibit a smaller or
comparable error with fewer patches to fabricate.\n\nRegistration Categor
