5.3.4.2 Bézier curves

Bézier curves used in VRR are rational Bézier curves. For each control point of the curve a rational weight is defined (1, by default) which influences the shape of the curve as well. The weights are the object's properties and can be modified in the Property editor.

• Segment

Creates a segment defined by the start point and the end point.

Type term: segment
Subtype term: segment
Hanger term: curve, start, end
Anchor term: start, end

• Quadratic Bézier curve

Creates a quadratic Bézier curve defined by three control points.

Type: bezier
Subtype: quadratic-bezier
Hangers: curve, controlpoint-1, controlpoint-3
Anchors: controlpoint-1, controlpoint-2, controlpoint-3

• Cubic Bézier curve

Creates a cubic Bézier curve defined by three control points.

Type: bezier Subtype: cubic-bezier Hangers: curve, controlpoint-1, controlpoint-4 Anchors: controlpoint-1, controlpoint-2, controlpoint-3, controlpoint-4
