Dynamic consistency under wide-angle omnidirectional transitions

Develop a method within the InSpatio-World spatiotemporal autoregressive framework to ensure multi-view consistency and spatiotemporal coherence of dynamic elements during wide-angle, omnidirectional view transitions.

Background

InSpatio-World integrates an implicit spatiotemporal cache with explicit geometry-aware constraints to enable real-time, controllable 4D roaming from a single video. While this approach provides strong structural anchors and supports large-scale displacement in static environments, its memory primarily captures structural information and does not persistently encode fine-grained textures in generated regions.

The authors note a remaining gap for dynamic content: during wide-angle, 360-degree transitions, maintaining multi-view consistency and spatiotemporal coherence of moving objects remains unresolved. Addressing this would extend the framework’s robustness from static scenes to complex dynamic environments with omnidirectional navigation.
