What is RVIZ
-
RViz (ROS 1) and RViz2 (ROS 2) are interactive visualization and debugging tools for the Robot Operating System (ROS).
-
They are used to visualize robot models, sensor data, coordinate frames (TF), maps, point clouds, and navigation information in real time.
-
They help developers monitor, analyze, and debug robot perception, localization, mapping, and navigation without directly inspecting raw ROS messages.
-
RViz is designed for ROS 1, while RViz2 is its successor for ROS 2, offering similar visualization capabilities with support for the ROS 2 architecture.
