How do I install RViz for ROS 2?

RViz is included with standard ROS 2 installations; download it via the official ROS 2 packages. For source builds, clone the ros2/rviz repo and use colcon with --merge-install, as per the developer guide.

RViz vs RQt: which is better for robot visualization?

RViz excels at 3D, real-time visualization of sensor data and models, while RQt is better for 2D plotting and GUI tools. Use RViz for interactive 3D debugging and RQt for logging or panel-based interfaces.

How to visualize point clouds in RViz?

Add a Point Cloud display from the Displays panel, then set the topic to your ROS 2 point cloud message. Configure properties like color and size in the panel for customized viewing.

Can I use RViz without ROS?

No, RViz is designed specifically for the ROS ecosystem and requires ROS 2 messaging for data input. For non-ROS projects, consider alternatives like Unity or custom visualization libraries.

What are the system requirements for running RViz smoothly?

RViz needs a moderate GPU for 3D rendering and sufficient RAM for handling large data streams like point clouds. Performance can degrade with high-frequency sensor data on lower-end systems.

How to create a custom display plugin for RViz?

Follow the plugin development guide: define a class inheriting from rviz_common::Display, implement update methods for ROS message handling, and register it via pluginlib for dynamic loading.

rviz

BSD-3-Clause-ClearC++

A 3D visualization tool for ROS 2 robots, enabling real-time sensor data display, robot model viewing, and interactive debugging.

What is rviz?

RViz is a 3D robot visualization tool for the Robot Operating System (ROS) that provides real-time visualization of sensor data, robot models, and coordinate transformations. It enables roboticists to debug, monitor, and interact with robotic systems by displaying laser scans, point clouds, camera feeds, TF frames, and other ROS messages in an interactive 3D environment.

Target Audience

Robotics engineers, researchers, and developers working with ROS 2 who need to visualize robot data, debug perception pipelines, validate robot models, or monitor system state during development and deployment.

Value Proposition

RViz is the standard, most comprehensive visualization tool for ROS, offering unmatched integration with ROS messaging, extensive built-in display types, and a flexible plugin architecture. Its real-time performance and deep ecosystem support make it indispensable for robotics development.

Teams relying on stereo visualization or other not-yet-ported ROS 1 features
Simple 2D data monitoring where lightweight tools like rqt_plot are sufficient

Pros & Cons

Pros

Extensive ROS Integration

Seamlessly visualizes real-time ROS 2 messages like laser scans, point clouds, and TF frames, making it indispensable for debugging robotics pipelines.

Plugin Architecture

Offers a well-defined plugin system for custom displays, tools, and transformation libraries, as documented in the plugin development guide.

Interactive Tools

Includes tools for setting navigation goals, measuring distances, and publishing points, enabling hands-on debugging and interaction with robot data.

Pluggable Transformations

Supports custom frame transformation plugins beyond tf2, with a dedicated Transformation panel for dynamic switching, enhancing flexibility.

Cons

Incomplete Feature Port

Lacks some ROS 1 features like stereo visualization, as noted in the README, which can hinder migration for teams dependent on those capabilities.

ROS Ecosystem Lock-in

Tightly coupled with ROS 2; building from source often requires the ROS 2 master branch, complicating setup for standalone or non-ROS environments.

Documentation Fragmentation

Relies partially on the ROS 1 wiki for documentation, which may be outdated or incomplete for ROS 2-specific features and changes.

rosbag2

Rosbag2 is the native recording and playback tool for ROS 2 systems, serving as the successor to the original ROS rosbag. It enables efficient capture and replay of timestamped communication data between ROS nodes, which is essential for debugging, analysis, and simulation in robotics development. ## Key Features - **Efficient Recording** — Designed to support complex robotic systems in real time with minimal overhead. - **Flexible Playback** — Replays recorded data with options for rate control, topic filtering, and service-based remote control. - **File Splitting** — Automatically splits bag files based on maximum size or duration thresholds during recording. - **Compression Support** — Offers optional compression (e.g., zstd) to reduce storage footprint. - **Snapshot Mode** — Maintains an in-memory circular buffer to capture and save data only on demand, useful for triggered events. - **QoS Overrides** — Allows custom Quality of Service profiles per topic via YAML configuration. - **Storage Plugins** — Supports multiple storage backends like MCAP and SQLite3 via a plugin architecture. - **Composable Nodes** — Recorder and player can be run as composable C++ nodes to enable intra-process communication for higher performance. ## Philosophy Rosbag2 prioritizes efficiency and flexibility, aiming to handle real-time data flows in complex robotic systems while providing a modular, plugin-based architecture for storage and serialization formats.
