terrain_gradient — DRIVE `terrain` op

• Data kinds: image2d × image2d × table → any

• Call: import fullseye as fs; fs.ledger.terrain_gradient(x, y, p: 'dict', course=None) (to call the implementation directly, import driveterrain; driveterrain.terrain_gradient(x, y, p: 'dict', course=None); from the registry, opsdrive.get("terrain_gradient"))

Usage

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

(∂z/∂x, ∂z/∂y) の閉形式: ∇(h·w) = w∇h + h·w′(d)·∇d、∇d = 最寄り点から外へ向く単位ベクトル。
