3D basics

In 3D, every object has a Position (where it is) and a Rotation (how it's oriented).

These are defined using three axes: X, Y, and Z.

Explore these concepts hands-on with the interactive cube below.

As you adjust the sliders, observe how the cube responds.

Understanding the controls

Position

• X: Moves the cube Left (-) / Right (+).
• Y: Moves the cube Down (-) / Up (+).
• Z: Moves the cube Closer (-) / Further (+).

Rotation

Defines how the cube is tilted around each axis.

• Rotation X (Pitch): Tilts the cube's "front" Up / Down (like nodding "yes").
• Rotation Y (Yaw): Turns the cube Left / Right (like shaking "no").
• Rotation Z (Roll): Tilts the cube Side-to-Side (like tilting your head).

Challenges

Now, try these challenges using the demo:

1. Place the cube in the top-left-far corner of its movement range.
2. Make the cube lie flat on one of its sides, with its original "top" surface pointing towards you.
3. Position the cube as if it's a car on the ground, facing right.

Mastering these transformations is the first step to creating dynamic 3D scenes!
