Dear ROS users, I am using the passthrough nodelet (link text) on a point cloud. Setting one field parameter (like in the tutorial) works. What I want to do is to use the nodelet to filter all the fields (x, y, z) at the same time. Since the param "filter_field_name" is only one, how I can achieve that? Thanks!

Although it doesn't seem to be currently documented on the wiki, the pcl_ros package also has a nodelet available for a crop box filter (feel free to add your own documentation!). You can see the description of the crop box filter here, and the dynamic reconfigure config file for the crop box filter should tell you what parameters to set and what they do.
