EQ Circles — the orbiting equalizer
The EQ Circles scene arranges several equalizer panels in a circle, each pointing toward the center of the scene. The whole structure rotates slowly, giving the impression of a sonic merry-go-round in 3D. Each panel is colored with a different hue from the HSL spectrum — a rainbow of frequencies in perpetual motion.
What you see
Multiple panels (each made of a series of thin bars arranged in an arc) together form a cylinder of equalizers that stretches upward with intensity. Each panel responds to its own frequency range with its signature color: red for sub-bass, orange for bass, yellow for low-mids, all the way to violet for ultra-highs.
Fifty-five small semi-transparent white cubes orbit at various distances and heights around the structure, animated by the overall energy of the music. During intense passages, they move away from the center; in silences, they draw closer.
Panoramic view
The scene's automatic rotation continuously scrolls different panels in front of the camera. Seen from the front, you observe a single full-height panel; seen from above, you discover the circular arrangement as a whole — like an equalizer mandala.
Technology
CIRC_PANELS panels distributed evenly over 360°, each containing CIRC_BARS BoxGeometry bars in an arc. Each panel's color is set via setHSL(p/CIRC_PANELS, 1, 0.5). Orbiting cubes each have their own angle, radius and phase, updated via sin/cos every frame.
