[vtkusers] Question again about the order of points for the vtkImageStencil

[Anja Ende]

Hi everyone,

Just a follow up on the thread from a couple of days back:

http://public.kitware.com/pipermail/vtkusers/2006-October/087856.html

What I am doing is basically just selecting points on the image and running
a spline through it. In the end, the loop is closed and the 2d surface is
extracted using vtkImageStencil.

Now, the points basically are randonly selected and can change direction
with successive points. The resulting surface also can either be concave or
convex. I am very confused as to what determines the orderness of points
(clockwise or anti clockise?) as the  surface can grow in either
direction...

Cheers,

Anja
