# Curves

In Varkon, a curve is a wireframe entity with start- and end position and a sense of direction going from start to end. Curves are composed by one or more segments. How many, depends on the curve type and how you create it. A spline for example, defined by 5 positions will consist of 4 segments.

Curves have parameters ranging from 0 to a number equal to the number of segments that make the curve. A curve with 5 segments will go from 0 to 5 in parameter. The parameter is not relative to arclength as it is for lines and arcs. Instead it relates exactly to the internal parameter used in the parametric curve representation. See: The VECTOR datatype and geometric positions for more information on how to access a position on a curve.
