12/3/6.htm  VB example of s-psi curve

When you click 'edge', a shape vaguely resembling an animal profile is 'stitched' by the edge-tracing routine.  A resulting s-psi cure is sshown in another window.  You can smooth this curve, while seeing the reconstructed shape.  You can also 'pack' it, reducing the number of points to 256.  The reconstructed shape is still recognsable.

The VB6 .frm file and also an .exe version are in this zip file.
