Hallo What is not working?
ST_ConvexHull only calculates in 2D but since it passes the z-values to the result it should work if your plane is coplanar and not vertical. If it is a vertical plane only one point per 2d point will be considered. But as long as each point has its own representaion in 2D xy plane it should work as I understand it. /Nicklas On Tue, 2011-06-07 at 12:25 +0200, [email protected] wrote: > Hi, > > I would like to ask a question : > I have set of point clouds and managed to do the segmentation.
