This page on rviz display types on the ros website mentions a attribute that the pointcloud type is "selectable". I'm not sure what that means exactly but it sounds like something I want.

I would like to display a pointcloud, and qualitatively analyse it. During this, I would like to select a point or a group of points through mouseclicks and do simple analysis like get the point coordinates or compute the group centroid etc.

Does rviz allow you to do that?

Thank you.

AFAIK, Rviz is mainly for visualization. What you want to do (select a point/group of points through mouseclicks, etc) should be done using PCL library or your private methods. Then you publish your results in Rviz for display.

Hmm. Do you know if I could get back stuff like the mouseclick locations, viewpoints, projections from rviz? Then I could go ahead and use that for my methods.

I did a quick search and this #q69019 turned up :) It seems like you can select a point and its position will be printed out.
