DisCoScene: Spatially Disentangled Generative Radiance Fields for Controllable 3D-aware Scene Synthesis

Xu, Yinghao, Chai, Menglei, Shi, Zifan et al.

Understand

Existing 3D-aware image synthesis approaches mainly focus on generating a single canonical object and show limited capacity in composing a complex scene containing a variety of objects.

  • This work presents DisCoScene: a 3Daware generative model for high-quality and controllable scene synthesis.
  • The key ingredient of our method is a very abstract object-level representation (i.e., 3D bounding boxes without semantic annotation) as the scene layout prior, which is simple to obtain, general to describe various scene contents, and yet informative to disentangle objects and background.
  • Moreover, it serves as an intuitive user control for scene editing.
