The nature of meteor shower (crossing of the dust trails [former cometary orbits] with the Earth's orbit).
3-D nature of the phenomenon: not every cometary passage causes meteor showers. Need a right crossing.
Why all meteor showers show maximum meteor rates only past midnight: because of the geometric orientation of the Earth's motion and Earth's rotation.
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.
