# voxeled layout — two Möbius hearts, 10 ft apart, with a crossfading show.
# Edit this file and re-run `npm run demo` (or point VOX_LAYOUT at another file).
name: two-hearts
units: mm

# Fixtures: reusable geometry, built by a registered type + params (see run.mjs FIXTURES).

    # The sculpture itself — the steel rails + rods from the heart's CAD (mobius-led-heart/cad),
    # exported to STL in mm, same frame as the ribbon. Drawn translucent around the LEDs; in the
    # simulator (S) it's an opaque occluder. Toggle with M. Files resolve relative to this layout.

# Instances: copies of a fixture placed in shared world space (translation mm, rotation deg).
# 10 ft = 3048 mm, centred on the origin → ±1524 mm in X.

# Show: scenes the mixer auto-crossfades between. Scenes 2 & 3 are the same wipe in the two
# coordinate spaces, so the crossfade itself shows the 10-ft gap being accounted for vs ignored.
