SUMMARY:A Simple Approach to Differentiable Rendering of SDFs
DESCRIPTION:Zichen Wang and Xi Deng (Cornell University), Ziyi Zhang and W
 enzel Jakob (EPFL), and Steve Marschner (Cornell University)\n\nWe present
  a simple algorithm for differentiable rendering of surfaces represented b
 y Signed Distance Fields (SDF), which makes it easy to integrate rendering
  into gradient-based optimization pipelines. To tackle visibility-related 
 derivatives that make rendering non-differentiable, existing physically ba
 sed differentiable rendering methods often rely on elaborate guiding data 
 structures or reparameterization with a global impact on variance. In this
  article, we investigate an alternative that embraces nonzero bias in exch
 ange for low variance and architectural simplicity. Our method expands the
  lower-dimensional boundary integral into a thin band that is easy to samp
 le when the underlying surface is represented by an SDF. We demonstrate th
 e performance and robustness of our formulation in end-to-end inverse rend
 ering tasks, where it obtains results that are competitive with or superio
 r to existing work.\n\nRegistration Category: Full Access, Full Access Sup
