fill_gaps — DRIVE `walkterrain` op

• Data kinds: depth → depth

• Call: import fullseye as fs; fs.ledger.fill_gaps(grid) (to call the implementation directly, import terrain; terrain.fill_gaps(grid); from the registry, opsdrive.get("fill_gaps"))

• GPU: none (CPU reference implementation only)

Usage

Fill nan cells with the nearest finite height (nearest-neighbour).

空の入力(grid が 0 要素)は形を保った空の配列を返す(理由: 埋める穴が無く、形だけを保つ)。An empty grid comes back as an empty grid of the same shape.
