function sampleShapeField

sampleShapeField(field: ShapeField, theta: number, phi: number) → number

The radius in a direction, bilinearly.

Used by the ingest's fidelity check and by anything that wants a surface height without building a mesh. The mesh builder does not go through this — it walks the grid it already has.
