Purpose
Usage
Click the smooth curve button to activate it, then click the curve to be
reparameterized.
Comments
Each curve has a parameterization that influences the shape of the curve. If
the parameterization is not adequate, then highly curved corners can occur.
smooth curve reparameterizes a curve according to the distance between the
control points.
Example
When building a symmetric closed curve, the curve inside the symmetric control
polygon can be made symmetrical using smooth curve.
