HeightfieldRequest

borderreadonly

Rings of samples outside the patch. Default HEIGHTFIELD_BORDER.

regionreadonly

resolutionreadonly

Vertices per side of the patch itself; see HEIGHTFIELD_RESOLUTION.

seabedreadonly

Whether the field is the seabed — drawnGroundElevation, the ground under any sea with the clamp left off — or the drawn surface, clamped up to the datum. The seabed is right only where the renderer lays a sheet over it at the datum; a mapped body has no sheet, its photograph is its sea, and an unclamped seabed under the photograph is a trench kilometers below the datum the ship lands on. Default false: clamped.
