Did you managed to use the relative path ? I have exactly the same problem, absolute path is working fine but the relati

Hello,

I am publishing data trough different publisher, mainly with visualization_msgs::Marker and nav_msgs::GridCells objects. I get a visualization in my RVIZ window and what I want to do is to save this visualization into an image of the size I want.

Do you know if there is a plug-in who can do that ? Or if there is some other way to do that ?

I don't want to do a screen shot because i would like the size of my image to be bigger than the actual definition of my screen.

Simple and clear! Thank you

I am using a tf::TransformListener listener to get the transformation between two frame in my c++ program. My tf Tree is as follow Parent -> Child1 ->Child2 . I am using the following line to get the transformation between Parent to Child1:

listener.lookupTransform(frame_parent, frame_child1, ros::Time(0), transform);

When I am displaying the /tf topic with rostopic echo /tf, I can see a transformation for Parent -> Child1 and a transformation from Child1 -> Child2.

My question is, can I get the transformation from Parent -> Child2 ? Can the TransformListener return a combination of transformations ? I wrote something like this:

listener.lookupTransform(frame_parent, frame_child2, ros::Time(0), transform);

Can TransformListener get the transformation of an indirect child I am using a tf::TransformListener listener to get the

Hello,

I am getting a from a rosbag a point cloud which as been register with a velodyne. I'm visualizing it with a PointCloud2 display type.

I have some artifacts on the result so I'm trying to understand exactly what is appending, but i don't understand what Intensity mean in the "Channel Name" field or in the "Color Transformer" field.

Does someone can help me understand what the intensity represent ? Is it the number of point at the same place ?
