What is a Whirl?
Begin with an arbitrary polygon. Construct a nested polygon by joining points that are a fractional distance along each edge. Repeat this process ad infinitum.
The vertices of the whirl form a logarithmic spiral, and they approximate a pursuit curve. The center of the spiral is the centroid of the polygon.
If the constructed polygon’s vertices lie on midpoints of the base polygon, then it’s called a midpoint polygon. If the constructed polygon has an even number of sides, then it’s called a derived polygon.
