A class to draw parametric curves. They are supposed to be given in cartesian coordinates, and conversion to polar coordinates will have to be done by the user beforehand.
The relevant part of the header is :
A range has to be defined, and the minimum number of points
defines the smallest parameter interval between two points.
By default, it is 200, but it could be a good policy to
take it larger. An adaptive (to be improved, I hope)
algorithm is used to add subpoints, by dichotomy, up to a
certain number of steps, which can be changed. (0 means
there is no adaptive algorithm used, and the
minimumNumberOfPoints is exactly the number of points
calculated and drawn.)
