Bezier curve
A Bézier curve is essentially a vector-based curve generated by mathematical formula. The precise formula used varies with the curve complexity. They are used to replace vectors between two or more nodes. The formulae for generating the vectors are still present, but not rendered - they are instead traversed as data for the curves. Using one vector as data produces a straight 'curve', Using two, produces a quadratic curve, three produce a cubic, et al.
These curves are the only means through vectors of producing true curves, and are sometimes assembled into complete 3D polygonal shapes called a beziergon. These shapes are complex, curving surfaces or 3D objects, usually without a single straight line in them.
