Globe Software

Complete interactive globe visualization system with hardware control, media playback, and web interface.

Overview

Globe Software is a complete system for controlling and visualizing content on a physical rotating globe display. This package includes both the FastAPI backend server and the React web interface as static files.

WARNING: This package is designed to be used on the Globe platform hardware - use on other systems may result in unexpected behaviour like forced network disconnects.

Features

  • Web Interface: React-based UI for controlling the globe (served as static files)
  • FastAPI Backend: High-performance async web server with REST API
  • Globe Visualization: Real-time 3D globe rendering with earth-viz
  • Media Management: Upload and manage video/image content with playlist support
  • Hardware Control: Interface with ESP32 (motor) and FPGA (display) hardware
  • Network Management: WiFi configuration, network switching, and access point mode
  • Automatic Updates: Online (PyPI) and offline (.whl) update support
  • Real-time Communication: WebSocket support for live status updates

Installation

Quick Install

pip install globe-server

Initial Setup

After installation, run the setup wizard to configure the system:

globe-server-setup

This will:

  • Create the ~/.globe-server/ directory structure
  • Download required static images for visualization
  • Prompt for configuration (ESP32 API key, WiFi credentials, etc.)

Production Deployment (Raspberry Pi)

For production deployment on Raspberry Pi, see the installation guide which covers:

  • Creating the installation directory and virtual environment
  • Installing as a systemd service
  • Automatic startup and update management

Usage

Starting the Server

# Start the server
globe-server

The server will start on http://localhost:8000 and serve:

  • Web interface at http://localhost:8000/
  • API documentation at http://localhost:8000/docs
  • Alternative API docs at http://localhost:8000/redoc

Accessing the Web Interface

Once the server is running, open your browser to:

  • http://localhost:8000 (local access)
  • http://<raspberry-pi-ip>:8000 (remote access)

The web interface provides:

  • Media upload and playlist management
  • Globe visualization controls
  • Motor speed and rotation control
  • Network and WiFi configuration
  • System settings and firmware updates

Command Line Options

# Start with default settings
globe-server

# Or use uvicorn directly for custom configuration
uvicorn globe_server.main:app --host 0.0.0.0 --port 8000 --reload

Configuration

The server stores configuration and data in ~/.globe-server/:

  • .env - Environment variables (API keys, WiFi credentials)
  • globe.db - SQLite database
  • media/ - Uploaded media files
  • updates/ - Software update packages (.whl files)
  • logs/ - Application logs

Key configuration settings (from globe_server.config):

  • GLOBE_DATA_DIR: ~/.globe-server (base directory)
  • GLOBE_MEDIA_DIRECTORY: Media storage location
  • UPDATE_DIRECTORY: Software update packages
  • MOTOR_RPM: Default motor rotation speed
  • ESP32_API_KEY: Authentication for ESP32 communication

API Endpoints

The REST API provides programmatic access to all features:

  • / - Web interface (static files)
  • /media/* - Media file management and playback
  • /playlist/* - Playlist operations
  • /motor/* - Motor control (ESP32)
  • /status/* - Server status and WebSocket updates
  • /settings/* - Server configuration
  • /update/* - Software and firmware updates (server, ESP32, FPGA)
  • /network/* - Network and WiFi management
  • /earth-viz/* - Globe visualization rendering

Full interactive API documentation available at /docs when server is running.

Software Updates

Globe Software supports both online and offline updates:

Online Updates (PyPI)

When connected to the internet, the system automatically checks for updates on startup (when using the systemd service).

Offline Updates

For systems without internet access:

  1. Download the update bundle (.whl files for the package and all dependencies)
  2. Copy all .whl files to ~/.globe-server/updates/
  3. Restart the server

The startup script will automatically install from local files if PyPI is unavailable.

Development

From Source
