When we search for a point located on boundary then the largest ID is returned, but I want all the IDs how can I do that?
Is there any other way to find it?

If it's a convex cloud, you can just use convhull(). If it is not convex, then you need to define what you mean by the boundary, since there are many 3D envelopes possible for a point cloud. You might consider alphashape(), however..

Did you intend to attach code or a plot? I see none.
In any case, my advice applies in 2D as well.
