Should do what I think your describing. It chooses a user defined number of landmarks along a curve, and interpolates (linearly) between coordinates. -Steve Frost ----- Original Message ---- From: morphmet <[EMAIL PROTECTED]> To: morphmet <morphmet@morphometrics.org> Sent: Thursday, November 8, 2007 1:27:31 PM Subject: Percent distance along a curve Hello all, Does anyone know of a program/method that would allow me to place points on a curve based on percent of the total distance from one end of the curve to the other? The data would be in paired xy coordinates. For example, if I have a curve made up of (x,y) points that is 10 cm in length, I would like to determine the coordinates of positions on that line at 10%, 20%, 30% etc. (i.e., every cm) of the total distance by interpolating between the coordinate pairs I already have.

How odd it is that anyone should not see that all observation must be for or against some view if it is to be of any service!" -Charles Darwin, in an 1861 letter to Henry Fawcett. -- Replies will be sent to the list.
