SUMMARY:Continuous deformation based panelization for design rationalizati
 on
DESCRIPTION:Technical Papers\n\nContinuous deformation based panelization 
 for design rationalization\n\nJadon, Thomaszewsky, Apolinarska, Poranne\n\
 nDesign rationalization is the process of simplifying a 3D shape to enable
  cost-efficient manufacturing. A common approach is  to approximate the in
 put shape by a collection of simple units, such as flat or spherical panel
 s, that are easy to manufacture and simple to assemble. This panelization 
 process typically involves a segmentation step, with each surface patch in
 tended to be replaced by a single unit, followed by an approximation stage
 , where the final shapes and locations of the units are determined. While 
 optimal panel parameters for given segments are readily determined, the di
 screte nature of segmentation---assigning surface elements to segments---p
 revents a continuous design optimization workflow. In this work, we propos
 e a differentiable reformulation of panelization that enables its use in g
 radient-based design optimization. Our approach is to treat panelization a
 s a smooth optimization problem, whose objective function encourages the s
 urface to locally deform towards best-matching units. This formulation ena
 bles a fully-differentiable rationalization process with implicit segmenta
 tion in which panels emerge automatically. We integrate our rationalizatio
 n process in a simple user interface allowing the designer to guide the op
 timization towards desired panelizations. We demonstrate the potential of 
 our approach on a diverse set of complex shapes and different panel types.
