CloudCompare is the way to go. Just save them as .PCD or any format readable from Cloud Compare and enjoy comparing ;)

This seems to be a linker problem. Therefore make sure that you have properly installed the library files or you are doi

Thanks a lot.

Here is the code I am using to broadcast a transform and publish the path of the same transform.

global_transform_.frame_id_ = "world";
global_transform_.child_frame_id_ = "base_link";
global_transform_.stamp_ = transform_in->header.stamp;
global_transform_.setRotation(q);
global_transform_.setOrigin(p);

broadcaster_.sendTransform(global_transform_);

geometry_msgs::PoseStamped pose;
pose.pose.position.x = p.x();
pose.pose.position.y = p.y();
pose.pose.position.z = p.z();
pose.pose.orientation.x = q.x();
pose.pose.orientation.y = q.y();
pose.pose.orientation.z = q.z();
pose.pose.orientation.x = q.w();

path_.header.frame_id = "world";
path_.header.stamp = transform_in->header.stamp;
path_.poses.push_back(pose);

path_pub_.publish(path_);

Surprisingly, the outcome of the orientation in RViz is different for the two corresponding frames even though I have used the same quaternion value for both (please see the image attached below).

Any idea what is causing this?

If you mean which IDE is more convenient to program in ROS, I would highly recommend CLion.

I am following line by line instructions from here http://wiki.ros.org/rosbag/Code%20API. myBag is rosbag::Bag type, it

Hi guys,

I do run the binaries of my ros node using: $ gdb node from within the binary folder of my package and I do set accordingly breakpoints but when the execution reaches the breakpoint and I want to list the code via List function, it shows me this:

(gdb) l

1 <built-in>: No such file or directory.

Has anyone faced this problem before? Could you please give me a hint what I may be doing wrong?

Thank you!

Hi guys,

I have configured the Eclipse as my IDE and I am having no problems during compile time for my ROS packages. Once I run or enter the Debug mode, if there is an image_transport object use, it will immediately cause runtime error showing this error message:

[rospack] Error: package 'image_transport' not found terminate called after throwing an instance of 'pluginlib::ClassLoaderException' what(): Unable to find package: image_transport

When I try to run the same node outside the Eclipse environment I have no such problems. Do you have any idea what might be causing this?

Thank you!

Still these packages remained unaffected. Anyway thank you for effort!

Hi guys,

Even though i have tried to uninstall ROS using sudo apt-get remove ros-groovy-*, still there are some remaining packages like: ros-groovy-bfl, ros-groovy-opencv2 ... etc. Did anybody know how to completely remove them because i want to try a fresh installation of ROS and i dont want to have something from the previous installation.

Thank you in advance!
