TRViz (Terminal RViz for ROS 2)

Lightweight Terminal/TUI 2D Navigation & Visualization Workstation for ROS 2
Designed for Headless Robots, Remote SSH Sessions, and Embedded Platforms

🌟 Key Features

• Terminal 2D Map Visualization: OccupancyGrid (/map) rendering with aspect-ratio correction and rotated map-origin support.
• Interactive 2D Pose Estimate (/initialpose): Set robot initial position & heading directly from the terminal without typing quaternions manually!
• Interactive 2D Nav Goal (/goal_pose): Click/drag to dispatch Nav2 goals directly inside your SSH session.
• Live TF & Sensor Overlay: Real-time robot pose tracking (/tf), LiDAR points (/scan), point clouds (/points), and frame-aware navigation paths (/plan).
• Interactive Viewport: Smooth zoom (+/-), pan (WASD or mouse drag), and auto-follow robot mode (F).
• Standalone Mock Simulation: Built-in simulator (ros2 run trviz mock_sim) for testing without a physical robot or Gazebo.

⚡ Instant One-Line Remote Execution (via PyPI & uvx)

No workspace build or manual source setup required! Run TRViz directly on your robot or workstation:

# 1. Run directly from PyPI via uvx (zero installation!)
uvx ros-trviz

# 2. Built-in subcommands (powered by wpycli)
uvx ros-trviz doctor              # Diagnose ROS 2 & terminal environment
uvx ros-trviz mock                # Run synthetic simulation node
uvx ros-trviz replay path/log.jsonl # Replay recorded state offline
uvx ros-trviz completion bash     # Generate shell auto-completion

# 3. Traditional pip install
pip install ros-trviz
trviz --render-mode half

Smart ROS Auto-Discovery: Even if you haven't run source /opt/ros/<distro>/setup.bash, TRViz automatically discovers installed ROS 2 distributions under /opt/ros/ and configures the environment transparently.

📦 Traditional Installation & Build (ROS 2 Workspace)

Prerequisites

• ROS 2 (Jazzy, Humble, Iron, etc.)
• Python 3.10+
• textual, rich, numpy, pyyaml, wpycli

# 1. Build the workspace
cd /home/wkqco/Workspace/ros/trviz
source /opt/ros/jazzy/setup.bash
colcon build --symlink-install
source install/setup.bash

🚀 Quick Start Guide

Launch Python Version

source /opt/ros/jazzy/setup.bash
source install/setup.bash
ros2 run trviz trviz
# Or use the new CLI directly:
trviz run --render-mode half

Launch High-Performance C++ Version (trviz_cpp)

source /opt/ros/jazzy/setup.bash
source install/setup.bash
ros2 run trviz_cpp trviz
