Hi,

I'm detecting planes in a point cloud by using RANSAC as described in 
the manual at 4.1:

http://doc.cgal.org/latest/Point_set_shape_detection_3/index.html#title4

This works very well.

Next, I want to iterate over all assigned points of each plane as 
described in 4.3. This works, but it seems as the input 
pointsWithNormals-vector is rearranged, and therefore the retrieved 
indices doesn't correspond to the original ordering of the vector.

Is there a way to keep the original ordering of the points? Or, if not, 
is it possible to store an additional information (the original ID) for 
each pointWithNormal?

Thomas
