Which type allows the segments on either side of the vertex to be at any angle?

• A. Corner
• B. Smooth
• C. Bezier
• D. Bezier Corner

Answer: (A)

At a spline vertex, the knot type controls how the curve behaves right there. The Corner knot lets the two sides meet at a sharp point with no shared tangent or curvature constraint, so the incoming and outgoing segments can point in completely different directions. That means the angle between them can be anything. Other types impose continuity or curvature: Smooth forces a single tangent across the vertex, Bezier and Bezier Corner use control handles to shape curvature around the point, which fixes how the sides relate to each other. So for having the segments on either side of the vertex at any angle, Corner is the best fit.
