I am new in PCL. I successfully run the Octree code from the link http://www.pointclouds.org/documentation/tutorials/octree.php#octree-search.

I have one question. Is this possible to control Octree subdivision? For example, I want to restrict subdivision within 1st level which means register all points within 1st eight children. If possible, how can I access each children`s points?

Thank you for better understanding of my problem.
