Interface: Scene3DDebugStats

A point-in-time snapshot of the 3D scene’s memory drivers, for profiling. Returned by the map’s 3D debug stats hook (globalThis.__mvxScene3DStats() when globalThis.__MVX_SCENE3D_DEBUG__ is set before the map loads). The Three.js counters are the best in-page proxy for GLB VRAM, which performance.memory (JS heap only) cannot see.

Properties

currentFloor

currentFloor: string

Current floor key the overlay/models are built for.
