fbm_height — DRIVE `terrain` op

• Data kinds: image2d × image2d × table → image2d

• Call: import fullseye as fs; fs.ledger.fbm_height(x, y, p: 'dict') -> 'np.ndarray' (to call the implementation directly, import driveterrain; driveterrain.fbm_height(x, y, p: 'dict') -> 'np.ndarray'; from the registry, opsdrive.get("fbm_height"))

Usage

Closed form of the fBm height: h(x, y) = Σ_k A_k cos(2π f_k (x cosθ_k + y sinθ_k) + φ_k) (table from fbm_params).

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
