globe.getHeight is a ray cast against the drawn tile's mesh and scene.sampleHeight a GPU depth render; several layers asked for them uncached and unbudgeted. The cache written for Transit moves to src/services/terrainSurface.js and is handed to every layer through the ground service, so layers share one cache and one read budget. - Rail reads each train on a ~4 m grid instead of every frame. - Local data layers read terrain floors through it and stop depth samples at 8 ms a frame. - Bike Share draws stations at once and finds their heights afterwards in 4 ms steps.
