Rviz Visual Tools

C++ API wrapper for displaying shapes and meshes in Rviz via helper functions that publish markers. Useful for displaying and debugging data. For more advanced robot visualization features, see the moveit_visual_tools which builds on this class.

This package includes:

Rviz Panel GUI to step through your code for debugging and testing
Rviz-based keyboard control for stepping through application
Easy to use helper functions for visualizing in Rviz fast
Basic geometric markers for Rviz
More complex geometric shapes such as coordinate frames, framed boxes, planes, paths, graphs
Ability to quickly choose standard colors and sizes
Tools to ensure proper connection to Rviz before publishing visualizations
Shortcuts to convert between different types of points and poses - ROS msgs, Eigen, tf, etc
Batch publishing capabilities to reduce over throttling ROS messages
A tf publishing helper class
An interactive marker helper class

Install

Ubuntu Debian

sudo apt-get install ros-melodic-rviz-visual-tools

Build from Source

Clone this repository into a catkin workspace, then use the rosdep install tool to automatically download its dependencies. Depending on your current version of ROS, use:

rosdep install --from-paths src --ignore-src --rosdistro melodic

Quick Start Demo

To see random shapes generated in Rviz, first launch Rviz:

roslaunch rviz_visual_tools demo_rviz.launch

Then start demo:

roslaunch rviz_visual_tools demo.launch

Code API

See the Doxygen documentation

Usage

We'll assume you will be using these helper functions within a class. Almost all of the functions assume you are publishing transforms in the world frame (whatever you call that e.g. /odom).

Initialize

Add to your includes:

#include <rviz_visual_tools/rviz_visual_tools.h>

Add to your class's member variables:

// For visualizing things in rviz
rviz_visual_tools::RvizVisualToolsPtr visual_tools_;

In your class' constructor add:

visual_tools_.reset(new rviz_visual_tools::RvizVisualTools("base_frame","/rviz_visual_markers"));

Change the first parameter to the name of your robot's base frame, and the second parameter to whatever name you'd like to use for the corresponding Rviz marker ROS topic.

Tools

Now in your code you can easily debug your code using visual markers in Rviz

Start rviz and create a new marker using the 'Add' button at the bottom right. Choose the marker topic to be the same as the topic you specified in the constructor.

Example Code

In the following snippet we create a pose at xyz (0.1, 0.1, 0.1) and rotate the pose down 45 degrees along the Y axis. Then we publish the pose as a arrow for visualziation in Rviz. Make sure your Rviz fixed frame is the same as the one chosen in the code.

// Create pose
Eigen::Isometry3d pose;
pose = Eigen::AngleAxisd(M_PI/4, Eigen::Vector3d::UnitY()); // rotate along X axis by 45 degrees
pose.translation() = Eigen::Vector3d( 0.1, 0.1, 0.1 ); // translate x,y,z

// Publish arrow vector of pose
ROS_INFO_STREAM_NAMED("test","Publishing Arrow");
visual_tools_->publishArrow(pose, rviz_visual_tools::RED, rviz_visual_tools::LARGE);

// Don't forget to trigger the publisher!
visual_tools_->trigger();

For more example code see rviz_visual_tools_demo.cpp

Rviz GUI Usage

Publishes on the topic of /rviz_visual_tools_gui

The buttons in the Joy message correspond to the following:

1 - Next
2 - Continue
3 - Break
4 - Stop

Note: only Next is fully implemented

Mouse-Based Control

Use the Rviz panel called "RvizVisualToolsGui" to step through your program.

Keyboard-Based Control

Switch to the "KeyTool" in the top of the Rviz window and use the following keyboard commands:

n: next
c or a: continue
b: break
s: stop

Helper Functions

Reset function

deleteAllMarkers() - tells Rviz to clear out all current markers from being displayed.

All markers must be triggered after being published, by calling the trigger() function. This allows batch publishing to be achieved by only calling after several markers have been created, greatly increasing the speed of your application. You can even explicitly tell rviz_visual_tools how often to publish via the triggerEvery(NUM_MARKERS) command:

trigger()
triggerEvery(20)

Conversion functions

convertPose
convertPoint32ToPose
convertPoseToPoint
convertPoint
convertPoint32
convertFromXYZRPY
convertToXYZRPY

Convenience functions

generateRandomPose
generateEmptyPose
dRand
fRand
iRand
getCenterPoint
getVectorBetweenPoints

Frame locking

This allows the markers to be automatically updated as the base frame moves without having to republish. You can enable it via enableFrameLocking() (this is not enabled by default).

Interactive Marker Helper Class

This class quickly gives you basic 6dof pose interactive marker funcitonality. A demo is available:

roslaunch rviz_visual_tools demo_rviz.launch
rosrun rviz_visual_tools imarker_simple_demo

TF Visual Tools

This tool lets you easily debug Eigen transforms in Rviz. Demo use:

rviz_visual_tools::TFVisualTools tf_visualizer;
Eigen::Isometry3d world_to_shelf_transform = Eigen::Isometry3d::Identity(); // or whatever value
tf_visualizer.publishTransform(world_to_shelf_transform, "world", "shelf");

Note: this is a work in progress

Testing and Linting

To run roslint, use the following command with catkin-tools:

catkin build --no-status --no-deps --this --make-args roslint

To run catkin lint, use the following command with catkin-tools:

catkin lint -W2

Use the following command with catkin-tools to run the small amount of available tests:

catkin run_tests --no-deps --this -i

Run with clang-tidy:

run-clang-tidy-4.0.py -clang-tidy-binary=/usr/lib/llvm-4.0/bin/clang-tidy -fix -p=/home/dave/ros/current/ws_moveit/build/rviz_visual_tools .

Docker Image

Dockerhub automatically creates a Docker for this repo. To run with GUI:

# This is not the safest way however, as you then compromise the access control to X server on your host
xhost +local:root # for the lazy and reckless
docker run -it --env="DISPLAY" --env="QT_X11_NO_MITSHM=1" --volume="/tmp/.X11-unix:/tmp/.X11-unix:rw" davetcoleman/rviz_visual_tools:melodic
export containerId=$(docker ps -l -q)
# Close security hole:
xhost -local:root

(Optional) To build the docker image locally for this repo, run in base of package:

docker build -t davetcoleman/rviz_visual_tools:melodic .
