terrain 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.tree_mesh(height: 'float' = 6.0, trunk_radius: 'float' = 0.15, crown_radius: 'float' = 1.8, kind: 'str' = 'broadleaf', n: 'int' = 8, color=None) -> 'dict' (to call the implementation directly, import driveterrain; driveterrain.tree_mesh(height: 'float' = 6.0, trunk_radius: 'float' = 0.15, crown_radius: 'float' = 1.8, kind: 'str' = 'broadleaf', n: 'int' = 8, color=None) -> 'dict'; from the registry, opsdrive.get("tree_mesh"))

手続き的な木: 幹 = 正 n 角柱(高さ 0.35·height)、樹冠 = 円錐(conifer)か回転楕円体(broadleaf、上下 0.65·height)。
返り値 `{"V", "F", "color" (M,3), "label" (13), "dims", "volume"}。volume` は閉形式: 幹 = ½ n r² sin(2π/n)·h_t、
円錐 = ⅓·½ n R² sin(2π/n)·h_c(多角形の底面なので厳密)、楕円体は内接なので mesh_signed_volume ≤ 4/3·π R² (h_c/2)。
