A 3D Isovist World Model -- Revealing a City's Unseen Geometry and Its Emergent Cross-City Signature
arXiv:2606.03609v1 Announce Type: cross Abstract: Embodied agents that navigate cities rely on world models that predict how their surroundings will change as they move. But for navigation, what matters is not what the buildings look like; it is where the agent can go. Most world models nonetheless predict appearance, learning how a scene looks rather than the space an agent can move through. Those that do target geometry, such as bird's-eye-view occupancy grids, flatten the three-dimensional environment onto a ground plane, discarding the above-ground and multi-level structure that shapes rea
The increasing sophistication of autonomous agents necessitates more effective and efficient world models, moving beyond traditional appearance-based or flattened geometric representations.
This development in 3D isovist world models directly addresses a fundamental limitation in robot navigation and understanding of complex urban environments, enabling more robust and intelligent agent behavior.
Autonomous agents will be able to perceive and interact with urban geometries in a more nuanced and human-like way, understanding traversable space and multi-level structures rather than just visual appearance or 2D occupancy.
