<title>Precession and Change of Zodiac Signs</title>
Due to the precession of the Earth orbital plane, the reference point of the Equatorial Coordinate, Vernal Equinox, marches across the celestial sphere. This causes the change of Right Ascension of celestial objects hence the change of zodiac signs in every 2,000 years. This simulation describes this phenomenon.
Important pending tasks (or notes/ideas) to complete the simulation.
These are technical prerequisites (3D model components) to create this simulation.
These are newly created components (functions, materials, cameras, etc.) from this topic simulation.
These are underlying astronomical concepts to teach with this simulated topic.
These are key scenes of the simulation; based on storyboard files.
