01 / Context

Project overview

3D Earth is designed around an interactive globe where geographic and orbital data explain a selected place. The repository documents a Three.js renderer, calculated day/night lighting, UTC-based solar position, live orbital elements propagated with SGP4, satellite groups, OpenStreetMap context, device geolocation, and timezone-aware local-time display.

02 / Scope

Documented scope

  • Interactive 3D globe with mouse, touch, and trackpad controls
  • Solar altitude/azimuth calculations and day/night terminator
  • Satellite tracking from published orbital elements
  • Geographic map, location, and timezone context

03 / Engineering

Technology and engineering areas

  • JavaScript
  • Three.js
  • WebGL
  • Satellite Tracking
