ScenePainter: Semantically Consistent Perpetual 3D Scene Generation with
  Concept Relation Alignment
Perpetual 3D scene generation aims to produce long-range and coherent 3D view
sequences, which is applicable for long-term video synthesis and 3D scene
reconstruction. Existing methods follow a "navigate-and-imagine" fashion and
rely on outpainting for successive view expansion. However, the generated view
sequences suffer from semantic drift issue derived from the accumulated
deviation of the outpainting module. To tackle this challenge, we propose
ScenePainter, a new framework for semantically consistent 3D scene generation,
which aligns the outpainter's scene-specific prior with the comprehension of
the current scene. To be specific, we introduce a hierarchical graph structure
dubbed SceneConceptGraph to construct relations among multi-level scene
concepts, which directs the outpainter for consistent novel views and can be
dynamically refined to enhance diversity. Extensive experiments demonstrate
that our framework overcomes the semantic drift issue and generates more
consistent and immersive 3D view sequences. Project Page:

ScenePainter addresses semantic drift in 3D scene generation by aligning scene-specific priors with current scene comprehension using a hierarchical graph structure.
