Tangents

Tangents define the in and out curvature of a knot's segments.

Tangents have a length and direction. Length determines how much that tangent affects the curvature of its respective segment. A large length value increases a tangent's influence on a segment's curvature and a small length decreases it. Direction determines where the tangent points to from its parent knot.

A spline or knot's tangent mode determines how their tangents are calculated. If a knot is in the Bezier tangent mode, then you can directly manipulate its tangents in the Scene view. If a knot is in the Auto or Linear tangent mode, its tangents are calculated automatically.
