ASSIST: Interactive Scene Nodes for Scalable and Realistic Indoor Simulation

Zhong, Zhide, Cao, Jiakai, Gu, Songen et al.

Understand

We present ASSIST, an object-wise neural radiance field as a panoptic representation for compositional and realistic simulation.

  • Central to our approach is a novel scene node data structure that stores the information of each object in a unified fashion, allowing online interaction in both intra- and cross-scene settings.
  • By incorporating a differentiable neural network along with the associated bounding box and semantic features, the proposed structure guarantees user-friendly interaction on independent objects to scale up novel view simulation.
  • Objects in the scene can be queried, added, duplicated, deleted, transformed, or swapped simply through mouse/keyboard controls or language instructions.
