What is a Bezier?Named after the French Mathematician who invented it, the Bezier is a line with tension that has two nodes, one for each end, and two "control points" that define points which "attract" the line. The further the control point is from the node it's associated with, the more tension is on that node and the sharper the line bends towards the node. Bezier curves can be drawn singly with DrawBezier or in connected groups using DrawBeziers. Figure 1 shows a Bezier with its associated control points. The control points are joined to the respective nodes with a dotted line and illustrate how the tension is created in the curve.
