Intent (Metaphor)

Turn live audio → spectral structure → visual poetry. See sound as a living organism (swarm/nerve impulses) rather than just bars.

Digital organism: point‑cloud “body” + audio “nervous impulses.”

Packages & Import

• Add Keijiro Pcx to Packages/manifest.json (scoped registry). Restart Unity to auto‑install.
• Import binary little‑endian .PLY into Assets/ → becomes PointCloudData.

Rendering options (pick 1):

1. PointCloudRenderer (simple, large clouds).
2. Mesh (points as mesh).
3. Texture2D position/color maps for VFX Graph integration.

VFX Wiring

• If using Pcx → Texture2D, bake Position/Color maps and sample in VFX Graph to initialize particle positions/colors.

• Expose float props Band0..Band7 (or BandsA/B). Use them to modulate Spawn Rate, Size, Turbulence, Trails.

• Example: bass (Band1–Band2) → density waves; highs (Band6–Band7) → shimmer/sparks.
