bounding box filter for pointclouds?

Hi, I was looking at laser_filters package and was wondering if there was a similar package for point clouds? I have a 360 3D LIDAR and want to exclude my robot (inside a static box relative to the LIDAR) from the output I am going to use. Is there an existing package to plug and play with like laser_filters?

Yes, there is: see the nodelets in pcl_ros (and linked tutorials).

They can be a little confusing to get working, but as long as you keep in mind they are all nodelets (with input and output topics), it should not be too difficult.

In the link there appear to be PassThrough filters that can filter within or beyond given X/Y/Z values - so I can see how you could use a series of 3 these to get all of the points within some orthogonal bounding box. But I don't know if you could you do what OP asked for and get all of the points that are outside of a bounding box with a series of planar filters?
