Subject: Fitting a curve into a 3D point cloud From: Stan Date: 29 Sep, 2010 14:58:05 Message: 1 of 10 
I have data that is made up of a 3d point cloud (x,y,z coordinates). It essentially looks like a curved tube. My problem is that I can't find a way to calculate the centerline of this "tube of points". I can only find information on fitting surfaces to 3d point clouds using least square methods.
