UVoxID

Universal Voxel Identifier (UVoxID) — a Python library for encoding and decoding spherical spatial coordinates at micrometer precision.

Think of it as a globally consistent voxel address system: every point in space has a permanent ID, valid from the Earth’s core to interstellar distances.

✨ Why UVoxID?

Floating-point coordinates drift.
Game engines rely on “floating origins.”
Robotics uses hacky spatial hashes.
Satellites juggle dozens of reference frames.

UVoxID fixes all that with a deterministic, integer-based addressing scheme:

• Universal: same scheme works for atoms, cities, and galaxies.
• Deterministic: encode/decode is exact, no rounding error.
• Persistent: voxel IDs never change, perfect for storage, sync, and replication.
• Spherical-native: gravity, orbits, and planetary geometry “just work.”

🔬 Resolution in UVoxID

UVoxID encodes space into deterministic voxels with two kinds of precision:

• Radial precision:

  • Always 1 µm (1/1000 mm), no matter the distance.
  • From Earth’s core to interstellar space, every radial step is exact.

• Angular precision:

  • Depends on radius r.
  • At small r → atomic/subatomic detail.
  • At large r → still millimeter-scale voxels, even across light-years.

📊 Example Resolutions

Distance (r)	Radial Resolution	Angular Resolution
Earth radius (~6,371 km)	1 µm	~2 × 10⁻¹² m (2 picometers, subatomic)
Moon distance (~384,000 km)	1 µm	~1 × 10⁻¹⁰ m (0.1 nanometer, X-ray scale)
1 AU (~150 million km)	1 µm	~5 × 10⁻⁸ m (50 nanometers, virus scale)
1 light year	1 µm	~3 × 10⁻³ m (3 millimeters)
2 light years (max)	1 µm	~6 × 10⁻³ m (6 millimeters)

⚡ Why This Matters

• No floats, no drift → everything is stored as integers.
• Near Earth, UVoxID gives atomic-level positioning.
• Across interstellar distances, UVoxID still holds positions with millimeter precision.
• This combination makes it ideal for:
  • physics & materials simulations,
  • planetary & orbital mechanics,
  • infinite game worlds,
  • robotics & autonomous navigation.

🚀 Use Cases

• Game Development:

  • Infinite open worlds without floating origin hacks.
  • Warp across star systems — arrive exactly where you should.
  • Persistent object positions across server restarts.

• Robotics & Drones:

  • Drop GPS/SLAM noise into a stable global grid.
  • Share maps between agents without coordinate drift.

• Satellites & Space Systems:

  • Orbital mechanics with deterministic precision.
  • Consistent addressing across LEO, GEO, Moon, Mars, and beyond.

• Scientific Simulation:

  • Track bacteria at µm scale or galaxies at light-year scale.
  • Perfect for physics engines, material degradation models, or climate sims.

• Digital Real Estate & Virtual Worlds:

  • Each voxel ID is globally unique and ownable.
  • Imagine buying a square meter on Mars… and knowing its exact ID forever.

🛠 Features

• 192-bit encoding: (radius, latitude, longitude) → one integer.
• String encodings: Base32, hex, or binary.
• Ephemeris support: Sun & Moon positions → UV, tides, day/night cycles.
• Earth model: WGS84 ellipsoid radius corrections.
• Scale introspection: compute what resolution a given ID represents.

📦 Installation

pip install uvoxid

🔍 Example

import uvoxid

EARTH_RADIUS_UM = 6_371_000_000_000  # mean radius in µm

# Encode position at Earth’s surface, equator, prime meridian
addr = uvoxid.encode_uvoxid(EARTH_RADIUS_UM, 0, 0)

print("Hex:", uvoxid.uvoxid_to_hex(addr))
print("Base32:", uvoxid.uvoxid_to_b32(addr))

r_um, lat, lon = uvoxid.decode_uvoxid(addr)
print("Decoded:", r_um, lat/1e6, lon/1e6)

Output:

Hex: 00059fb8c83f1000-00000000055d4a80-0000000000aba950
Base32: uvoxid:AAAALS25GEPAA-AAAAAAAFLVFIA-AAAAAAAKXKKQA
Decoded: 6371000000000 0.0 0.0

📖 Roadmap

• Planetary/stellar models beyond Earth/Moon/Sun.
• Python bindings for Rust/C++ core for performance.
• Optional Morton-code compatibility for indexing.
• Support for >192-bit scales (atomic → galactic cluster).
