    "walk" on elipse

    I'm not shure if this is university level, but here goes.

    I have an elipse, and an arbitrary point on it.
    What I want is to walk a specific distance along the elipse, from the givin point, and then get the point at that location.

    Anyone here got a formula for that?

    I don't have one (sorry) - and I think it is rather unlikely anyone else has. This is because the length of an elliptical arc leads to an elliptical integral that cannot be expressed by a combination of simple functions. What you need is a kind of inverse of that integral (as a function of its limits): which is likely to be even worse than the elliptical integral itself (but I may be mistaken).
