Eon's moon exists — now he wants it to move. Time for two of the most-used tools in all of 3D: rotation and scale.
Two essential moves
- Rotate — turn an object around (spin the moon).
- Scale — make an object bigger or smaller (size the moon and the planet).
With a brand-new mouse each, Eon and his dad can both control the scene — a little pair-building team.
Building an orbit (with a sci-fi twist)
Eon wants his moon to orbit — to circle around a planet, the way our real Moon circles Earth. For fun, they name their worlds after the movie Avatar: the moon Pandora orbiting the giant planet Polyphemus. (In the film, Pandora really is a moon, not a planet — a neat bit of real astronomy hiding in a sci-fi story.)
Scale sets how big each world is; rotation and orbit set how they move. Together they bring a dead model to life.
Try it
Hold a small ball (the moon) and walk it in a circle around a bigger ball (the planet) on a table. That circling path is an orbit — exactly what Eon is animating in Blender.
