tile_params — DRIVE inf op

• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.tile_params(tile: 'float' = 200.0, cells: 'int' = 8, relief: 'float' = 6.0, road_width: 'float' = 7.0, flat: 'float' = 18.0, blend: 'float' = 20.0, p_road: 'float' = 0.85, jitter: 'float' = 0.25, seed: 'int' = 20261001) -> 'dict' (to call the implementation directly, import driveinf; driveinf.tile_params(tile: 'float' = 200.0, cells: 'int' = 8, relief: 'float' = 6.0, road_width: 'float' = 7.0, flat: 'float' = 18.0, blend: 'float' = 20.0, p_road: 'float' = 0.85, jitter: 'float' = 0.25, seed: 'int' = 20261001) -> 'dict'; from the registry, opsdrive.get("tile_params"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

区画の表。`tile = 一辺 [m]、cells = 区画あたりの格子の升目数(起伏の波長 ≈ tile/cells)、relief` = 起伏の振幅 [m]、

`road_width [m]、道から flat m は平ら、そこから blend` m で起伏へ戻す(★flat は地面の格子の三角形が道に掛かっても

地面が道より上に出ない幅: 道幅の半分 + 格子の対角 —— 10 m の格子で 3.5 + 14.1 ≈ 18 m。6 m では道が地面に埋もれた)、`p_road` = 辺を道が横切る確率、

`jitter = 区画の中の分岐点のずらし(区画の一辺に対する割合)、seed` = 世界の種。
