SUMMARY:Differentiable Rendering of Parametric Geometry
DESCRIPTION:Technical Papers\n\nMarkus Worchel and Marc Alexa (TU Berlin)\
 n\nWe propose an efficient method for differentiable rendering of parametr
 ic surfaces and curves, which enables their use in inverse graphics proble
 ms. Our central observation is that a representative triangle mesh can be 
 extracted from a continuous parametric object in a differentiable and effi
 cient way. We derive differentiable meshing operators for surfaces and cur
 ves that provide varying levels of approximation granularity. With triangl
 e mesh approximations, we can readily leverage existing machinery for diff
 erentiable mesh rendering to handle parametric geometry. Naively combining
  differentiable tessellation with inverse graphics settings lacks robustne
 ss and is prone to reaching undesirable local minima. To this end, we draw
  a connection between our setting and the optimization of triangle meshes 
 in inverse graphics and present a set of optimization techniques, includin
 g regularizations and coarse-to-fine schemes. We show the viability and ef
 ficiency of our method in a set of image-based computer-aided design appli
 cations.\n\nRegistration Category: Full Access\n\nSession Chair: Marc Stam
