Pre-programmed deformable material
Taisuke Ohshima, Tomohiro Tachi, Yasushi Yamaguchi
“Pre-programmed deformable material” is a material which transforms into preprogrammed shape. It’s flexible in one preprogrammed deformation but stiff in the other deformation. The transformation into freeform curved surfaces from flat state is difficult because it should have three different Poisson’s ratio within one material. The Poisson’s ratio is related to Gaussian curvature in surfaces of deformation, ie. positive Poisson’s ratio realizes curved surfaces whose Gaussian curvature is negative and negative Poisson’s ratio realized curved surfaces whose Gaussian curvature is positive. Proposed material has explicitly distributed Poisson’s ratio and realizes double curved freeform surfaces.
Digital Modeling Contest Works (Web 3D)
We have set up a gallery of historic prizes and award-wining works in past Digital Modeling Contests. Some of these works can be viewed in 3D virtual spaces using Web 3D technology "XVL Technology".
