Implementing Curvature Flow

For anyone interested in learning more about the 1D curvature flows we saw today in class, there’s an assignment (and some notes) from a previous year’s class here:

Curvature Flow

In fact, it wouldn’t be hard to implement in the same code framework we’re using for the class, since you can think of a plane curve as a “mesh” consisting of a single flat polygon with many edges.

The paper I mentioned on discrete curve shortening with no crossings is:

Hass and Scott, “Shortening Curves on Surfaces”, Topology 33, (1994) 25-43.

It would be fun to see an implementation of something like this on a surface (I’ve never done it myself!).
