tile_height — DRIVE inf op

• Data kinds: any × any × table → any

• Call: import fullseye as fs; fs.ledger.tile_height(i: 'int', j: 'int', x, y, tp: 'dict') -> 'np.ndarray' (to call the implementation directly, import driveinf; driveinf.tile_height(i: 'int', j: 'int', x, y, tp: 'dict') -> 'np.ndarray'; from the registry, opsdrive.get("tile_height"))

Usage

Ground height [m] at point (x, y) in tile (i, j): Perlin noise on the global integer grid × relief, flat around roads (0 up to flat m, smoothstep over blend m). Grid index = tile index × cells + cell index (exact in integers); interpolation uses only the fraction within the cell — continuous across seams, and no loss of digits far away.
