Reading the Cube

A cube is the marker you place in your immersive space.

The cube

Each cube is a see‑through box 10 cm (about 4 inches) on a side, so it never hides what is behind it. Every window and every measurement reads from the cube's exact center (pivot point), not its surface.

The face labels

Three faces are labeled so you can always tell which way a cube is turned:

• top — the upward face, drawn in green. It marks the cube's +Y (up) side.
• front — drawn in cyan (light blue). It faces away from you and marks the cube's -Z side.
• right — drawn in red. It marks the cube's +X (right) side.

At zero rotation, top points up, front points away, and right points to your right. As you turn the cube by pinching with both hands, watch the cube window to see the numbers.

The letter

Each cube gets a letter from A to L in the order it is placed: the first is A, the next B, and so on. That letter names the cube everywhere — on its window footer ("LINKED TO CUBE A"), on the measurement windows ("Cube A to Cube C"), and in the exports.

The pivot point

A small bright white pivot point marker sits at the dead center of the cube. Every distance and angle is measured from that one spot, so line it up with whatever you are measuring — a corner, a screw, the middle of a screen. You can hide or show it. See Action - Show the Pivot Point and Axes, and Concept - Pivot Point.

The axes

Three colored axis lines radiate from the pivot, each about half the cube's height, with labels at their tips:

• X line — red, labeled X- and X+.
• Y line — green, labeled Y- and Y+.
• Z line — blue (cyan), labeled Z- and Z+.

Above the Y axis, World or Local tells you which frame the axes are drawn in. The cube's letter is labeled under the Y axis.

The window above it

The cube window floats above the cube. It holds that cube's buttons and a live readout of its position and rotation in both World and Local space. The Local Space card carries an EDIT control for typing those numbers in exactly (see Action - Edit a Cube by Numbers). When space is tight, minimize the window to a small tag that still shows the cube's letter and location. See Reading a Measurement Window for the panel that sits between two cubes, and Action - Minimize, Maximize, and Resize Windows.

How cubes behave at a distance

A cube will appear larger at a distance but its true size remains. Windows grow with distance so they stay readable, and they fade when you are not looking at them.
