WorldStream streams open-ended 3D worlds with persistent editable state
Original title: WorldStream: Streaming Interactive 3D Worlds with Hierarchical Planning and Persistent State
Hierarchical planners compile terrain ahead of the player while one world record restores prior visits and edits.
WorldStream is an open-ended 3D world model that extends terrain beyond a fixed map, acts on language in the running world, and restores visited places with their edits. A hierarchical planner emits macro structure for settlements, ecology, transport, and hydrology, then micro tile semantics. Deterministic code compiles accepted plans into terrain and entities, while plans run ahead of the user and distant geometry is released. One world record keeps plans, seeds, identities, mutable state, and edits so returning tiles can be recompiled.
- Macro plans cover groups of tiles; micro plans specialize individual tiles.
- Compilation runs only where movement will soon need geometry.
- The same record grounds NPC updates and edits to the present region.
- Intent can be attached to regions that have not yet been planned.

We present WorldStream, an open-ended 3D world model with three simultaneous capabilities: it extends playable terrain beyond any pre-specified map, acts on open-ended language in the running world, and restores visited places with their edits.
