RVIZ - Display pointcloud by Id

edit

Good morning,

I would like to know if it is possible to display on RVIZ a pointcloud with a color transformer based on point Id? This could make easier to display whether the pointcloud one's would like to construct is correctly made (ex: index the right point to the right position even after some transformation between frames).

I could easily get that it is possible to hardcode a RGB pointcloud and change the color according to their index, then send to RVIZ, but I am thinking about something already existing in RVIZ, as an option.

Does it already exist? Or is it possible using a custom plugin?

Thank you for your researches, this might make my life easier ;)
