SurfacePlacement

SurfacePlacement = "draped-billboarded" | "draped-flat" | "absolute" | "relative" | "relative-to-scene"

Defined in: src/ExpoArcgis.types.ts:206

How a geometry’s z value is interpreted against the scene’s surface. Mirrors SurfacePlacement.

  • draped-billboarded — z ignored; drawn on the surface, always facing the camera. The default.
  • draped-flat — z ignored; drawn lying on the surface, so it tilts with the terrain.
  • absolute — z is height above sea level, independent of the surface.
  • relative — z is height above the surface.
  • relative-to-scene — z is height above scene layers (buildings, meshes) where present, falling back to the surface elsewhere.
