Overview
When a world spans tens or hundreds of square kilometers, loading the entire map at once is neither practical nor necessary. World Partition automatically divides the world into grid cells and dynamically streams them in and out based on camera view distance and priority, keeping very large worlds seamless, smooth, and memory-bounded.
Key Capabilities
- Automatic grid partitioning: the world is split into cells with no manual level splitting.
- View-distance streaming: only cells near the player/camera are loaded; distant cells stream in on demand.
- Data Layers: overlay or hide content by function (day/night, buildings/pipelines).
- Collaboration-friendly: partition-grained editing reduces asset conflicts across teams.
- Stable at scale: paired with double-precision rendering, distant cells remain accurate.
Use Cases
- City- / region-scale digital twins and open worlds.
- Large-scale simulation and situational visualization.
- Projects where multiple teams edit the same large world in parallel.

World Partition typically combines with enhanced double-precision rendering and Cesium geospatial to form a complete “real geography + large world + high precision” solution; for large- or multi-display delivery, add multi-channel rendering.
