Hi everyone,
Does there exist a way view a ROS message from a file (non-rosbag)
directly in rviz? I was thinking that would be a nice addition.
Basically, I'm looking for a C++ (or python) API that allows the user to
save a single message of arbitrary type to a file. The rviz message
display can then be modified to load messages from a file, in addition
to the existing functionality to subscribe to a topic. This could
perhaps be implemented using URI's, for example
topic://scan
vs
file:///home/username/ros/myscan.rosmsg
This would be useful in many situations, especially for examining large
saved images, 2d/3d maps, pointclouds, etc.
Has any of this been implemented, and does anyone have comments on this
idea?
Cheers,
Ivan
