building_prisms — DRIVE `japan` op

• Data kinds: any → any

• Call: import fullseye as fs; fs.ledger.building_prisms(buildings: 'Iterable[dict[str, Any]]', *, color_fn: 'Callable[[dict[str, Any]], Sequence[float]] | None' = None, base_z: 'float | None' = 0.0, roof_shade: 'float' = 0.92) -> 'tuple[np.ndarray, np.ndarray, np.ndarray, np.ndarray]' (to call the implementation directly, import driveplateau; driveplateau.building_prisms(buildings: 'Iterable[dict[str, Any]]', *, color_fn: 'Callable[[dict[str, Any]], Sequence[float]] | None' = None, base_z: 'float | None' = 0.0, roof_shade: 'float' = 0.92) -> 'tuple[np.ndarray, np.ndarray, np.ndarray, np.ndarray]'; from the registry, opsdrive.get("building_prisms"))

Usage

Combines a list of buildings into an extruded-prism mesh.

> The detailed description below is the original text — the summary and the headings are translated.

Args:

buildings: plateau_parse の buildings(footprint, height, ground_z)。

color_fn: building -> (r,g,b) 0..1。None なら _default_building_color。

base_z: 全建物の底 z [m]。None なら各建物の ground_z を使う(起伏のある世界向け)。

自前の平らな道路世界には 0.0 が合う。

roof_shade: 屋根面の色の倍率(側面と見分けるための控えめな陰)。

Returns:

(V (n,3) float64, F (m,3) int64, colors (m,3) float64 0..1, ids (m,) int64)。ids[f] は面 f が属する建物の番号(入力列の添字)。建物が 0 件なら各配列は空。

Raises:

ValueError: color_fn の返り値が RGB 3 要素 0..1 でない、建物の footprint/height が不正。
