Optimizing heterogeneous elastic material distributions on 3D models

Published in Computer-Aided Design, vol. 175, 103748 (SPM 2024 special issue), 2024

A pipeline for designing heterogeneous elastic material distributions on 3D parts so that they exhibit desired deformation behaviour: interactive deformation design, automatic deformation generation, and a graph-cut + ADMM optimization over a finite set of base materials. Applied to 3D-printed customized insoles.
