Find inflection points on polylines

Hi there,

Has anyone seen a script--or know of a Python function or class--that gets the inflection points along a polyline? (Inflection is the point at which the line changes direction.) I saw an "iPoint" in a VB script but I don't know VB, and I'm using ArcGIS 10 so I'd need to do this in Python anyway. There is an AddIn, called "Curves and Lines," which grabs the inflection points but goes on to grab all points where the polyline bends and then splits up the line, which I don't want. If it were written in Python I'd just look at that part of the code, but it's an AddIn so I can't look at the coding.

Here's the link to Curves and Lines, just for fun:


Thanks for any suggestions!
