  1. Default for those of you expert in the clothoid / Cornu Spiral

    Can you point me to references on these topics? (Or answer the
    question directly?)

    1. Given an point and clothoid, how do I find the nearest point on the
    clothoid to the given point?

    2. Given two clothoids, how do I find their intersection (if it
    exists)?

    3. Are there standard algorithms for converting to and from Bezier
    curves and clothoids? How about converting between lines/arcs to/from
    clothoids?

    4. Is there a proven way to visually edit a clothoid similar to the
    way you would edit control points on a Bezier curve?

    Thanks for your time.

    Sorry for the multiple posts. I swear it was the fault of Mr. Google
    and his groups.

    No problem. I suggest you contact Raph directly with your questions,
    and/or examine his work in detail.
