Returns the curvature of the curve at the given point. The curvature is the inverse of the radius of curvature at the point. The point must be on the curve.
curvature ( curve As Part, _
p1 As Point ) As Number
| Argument | Type | Description |
|---|---|---|
| curve | part | Must be a kind of curveMixin. |
| p1 | point | A point on the curve that defines the location at which the curvature is computed. |
