Abstract
Differentiable rendering of translucent objects with respect to their shapes has been a long-standing problem. State-of-theart methods require detecting object silhouettes or specifying change rates inside translucent objects-both of which can be expensive for translucent objects with complex shapes. In this paper, we address this problem for translucent objects with no refractive or reflective boundaries. By reparameterizing interior components of differential path integrals, our new formulation does not require change rates to be specified in the interior of objects. Further, we introduce new Monte Carlo estimators based on this formulation that do not require explicit detection of object silhouettes.
