Double-precision coordinates
Engine-wide 64-bit large-world coordinates keep sub-millimeter accuracy at 100 km — no distant jitter.
Rebuilding Virtual Worlds in Double Precision
A closed-source commercial 3D engine built on open-source O3DE. On top of that foundation we add in-house World Streaming, mesh terrain, AI decision-making and cloud streaming — for open worlds, digital twins and industrial simulation.
Highlights
Core features
World Streaming
Automatic cell streaming, HLOD proxies and content layers for huge open worlds and city-scale scenes.
PolyTerrain mesh terrain
True 3D mesh terrain with a non-destructive modifier stack — cliffs, caves and GIS elevation import.
HTN AI system
Hierarchical Task Network planner plus a visual node editor so designers can author agent behavior.
Navigation3D
Sparse-voxel volumetric navigation for flight, underwater and mixed ground–air pathfinding.
Dawn Stream
Cloud rendering with interactive browser delivery — one GPU host and one web link.
Commercial delivery & asset protection
Closed-source SDK delivery plus full-path AES-256 Pak encryption to protect shipped assets.
Modular Gem architecture
Continuously synced with open-source O3DE — modular, deeply customizable, with commercial licensing and support.
Domestic OS & multi-platform
Windows / Linux today; Kylin and UOS support, with HarmonyOS on the roadmap.

Use cases
Dawn Engine fits scenarios that demand coordinate precision, large scenes and commercial delivery:
- Open-world games: World Streaming plus PolyTerrain true-3D terrain, with no jitter at distance.
- Digital twins: city- and campus-scale twin visualization, operable in the browser via Dawn Stream.
- XR applications: stable spatial precision for immersive experiences.
Roadmap capabilities
The following capabilities have completed system design and advance on the product roadmap (communication only — not contractual delivery commitments):
- ClusterDisplay multi-screen cluster rendering: synchronized multi-machine, multi-display output for CAVE, video walls and simulation cockpits.
- Vehicle physics: wheeled / tracked vehicle physics with data-driven setup.
- Cesium geospatial, water system, HarmonyOS: aimed at digital twins and domestic platform requirements.
