SDFDiff: Differentiable Rendering of Signed Distance Fields for 3D Shape Optimization

Jiang, Yue, Ji, Dantong, Han, Zhizhong et al.

Understand

We propose SDFDiff, a novel approach for image-based shape optimization using differentiable rendering of 3D shapes represented by signed distance functions (SDFs).

  • Compared to other representations, SDFs have the advantage that they can represent shapes with arbitrary topology, and that they guarantee watertight surfaces.
  • We apply our approach to the problem of multi-view 3D reconstruction, where we achieve high reconstruction quality and can capture complex topology of 3D objects.
  • In addition, we employ a multi-resolution strategy to obtain a robust optimization algorithm.
