# 3DGS Engineering Guide (Router) > **Architecture**: Axis-driven static/dynamic router. Do NOT try to apply the engineering guidance from memory or from this router alone. Always load fragments from disk as described below. ## Step 1 — Detect Request Axes Analyze the user's request to determine axis values: ### Axis: domain | User Intent | domain value | |-------------|-------------| | Autonomous driving simulation, sensor sim | autonomous-driving | | Digital twin, smart city, GIS | digital-twin | | Cultural heritage, museum, 3D archiving | culture | | Film, game production, virtual production | film-games | | E-commerce, 3D product display, WebAR | ecommerce | | Industrial inspection, drone survey | industrial | | AR/VR/MR headsets, spatial computing | ar-vr | | BIM, architecture, as-built verification | bim | | Robotics, embodied AI, manipulation | robotics | | Military simulation, defense | military | | World model, interactive 3D world | world-model | | Unspecified or broad engineering question | all | ### Axis: focus | User Intent | focus value | |-------------|-------------| | Data acquisition, reconstruction, deployment pipeline | pipeline | | Quality assurance, scalability, cross-platform | best-practices | | Debugging artifacts, OOM, deployment failures | pitfalls | | Choosing tools by use case/platform/scale | decision-tree | | Specific technology stack info (formats, compression, engines) | tech-stack | | GIS integration, spatial analysis, S3M/Cesium | gis-to...
