SUMMARY:DR-Occluder: Generating Occluders using Differentiable Rendering
DESCRIPTION:Jiaxian Wu, Yue Lin, and Dehui Lu (NetEase Games AI Lab)\n\nTh
 e target of the occluder is to use very few faces to maintain similar occl
 usion properties of the original 3D model.\nIn this paper, we present DR-O
 ccluder, a novel coarse-to-fine framework for occluder generation that lev
 erages differentiable rendering to optimize a triangle set to an occluder.
  Unlike prior work, which has not utilized differentiable rendering for th
 is task, our approach provides the ability to optimize a 3D shape to defin
 ed targets. Given a 3D model as input, our method first projects it to sil
 houette images, which are then processed by a convolution network to outpu
 t a group of vertex offsets. These offsets are used to transform a group o
 f distributed triangles into a preliminary occluder, which is further opti
 mized by differentiable rendering. Finally, triangles whose area is smalle
 r than a threshold are removed to obtain the final occluder. Our extensive
  experiments demonstrate that DR-Occluder significantly outperforms state-
 of-the-art methods in terms of occlusion quality. Furthermore, we compare 
 the performance of our method with other approaches in a commercial engine
 , providing compelling evidence of its effectiveness.\n\nRegistration Cate
