Developability-preserved Free-form Deformation of Assembled Patches
(The Eurographics Association, 2004)
A novel and practical approach is presented in this paper that solves a constrained free-form deformation (FFD) problem where the developability of the tessellated embedded surface patches is preserved during the lattice ...
Tolerance Envelopes of Planar Parametric Part Models
(The Eurographics Association, 2004)
We present a framework for the systematic study of parametric variation in planar mechanical parts and for ef ciently computing approximations of their tolerance envelopes. Part features are speci ed by explicit functions ...
