摘要:
We propose SDFDiff, a novel approach for image-based shape optimization using differentiable rendering of 3D shapes represented by signed distance functions
and We apply our approach to the problem of multi-view 3D reconstruction,
SDF表示三维模型的优点: arbitrary topology, guarantee watertight surfaces
简而言之:1、采用SDF表示三维模型 2、使用 3D differentiable rendering 来进行shape potimization
