| Member | Description |
|---|---|
| Bezier | A third degree cubic Bezier curve. A non-linear segment defined by four control points. The Bezier curve starts at control point 0 (start point) and ends at control point 3 (end point) The start point and control point 1 define the tangent at the start point. Control point 2 and the end point define the tangent at the end point. The length of these tangent lines and position of the 4 control points determines the shape of the created Bezier curve. |
| EllipticArc | An elliptic arc is the portion of the boundary of a 2D ellipse that connects two points. |
| Line | A straight line segment between a start point and end point. |
