BSP-Net: Generating Compact Meshes via Binary Space Partitioning

Chen, Zhiqin, Tagliasacchi, Andrea, Zhang, Hao

Understand

Polygonal meshes are ubiquitous in the digital 3D domain, yet they have only played a minor role in the deep learning revolution.

  • Leading methods for learning generative models of shapes rely on implicit functions, and generate meshes only after expensive iso-surfacing routines.
  • To overcome these challenges, we are inspired by a classical spatial data structure from computer graphics, Binary Space Partitioning (BSP), to facilitate 3D learning.
  • The core ingredient of BSP is an operation for recursive subdivision of space to obtain convex sets.
