InfiniCity: Infinite-Scale City Synthesis 2023

  1. generates arbitrary-scale 2D maps from the bird’s-eye view.
  2. an octree-based voxel completion module lifts the generated 2D map to 3D octrees.
  3. a voxel-based neural rendering module texturizes the voxels and renders 2D images.

CityDreamer: Compositional Generative Model of Unbounded 3D Cities 2023. handles the diversity of buildings in urban environments.
