Higher-Dimensional Interpretations¶

Several CPS structures have natural interpretations in 3 or more dimensions. The Hexany’s generating tetrad is actually a 2D projection of a tetrahedron. The asterisk-based master sets represent orthogonal axes in N-dimensional space.

3D views start oriented to match the 2D projection; rotate to reveal depth.

3D Tetrad / Hexany¶

Tetrad 3D¶

Regular tetrahedron. The Hexany’s generating geometry lifted into 3D.

print('GENERATING GEOMETRY: Tetrad 3D')
plot(MasterSet.tetrad_3d(), figsize=(7,7))

GENERATING GEOMETRY: Tetrad 3D

factors = (1, 3, 5, 7)

for r in (2,):
    cps = CombinationProductSet(factors, r=r, master_set='tetrad_3d')
    n = len(cps.ratios)
    print(f'Tetrad 3D CPS  r={r}  ({n} notes)')
    if r == 2: print('  (= Hexany with this master set)')
    print('Ratios:', *[str(x) for x in cps.ratios])
    plot(cps, node_size=25, text_size=9, figsize=(8,8))
    print()

Tetrad 3D CPS  r=2  (6 notes)
  (= Hexany with this master set)
Ratios: 35/32 5/4 21/16 3/2 7/4 15/8

N-D Asterisk / Eikosany¶

Each spoke of the asterisk is an orthogonal axis in 5D space. MDS projects to 3D for visualization.

Asterisk N-D¶

5D asterisk—each spoke is an orthogonal axis.

print('GENERATING GEOMETRY: Asterisk N-D')
plot(MasterSet.asterisk_nd(), figsize=(7,7))

    print(f'Asterisk N-D CPS  r={r}  ({n} notes)')

    if r == 3: print('  (= Eikosany with this master set)')
    print('Ratios:', *[str(x) for x in cps.ratios])
    plot(cps, node_size=20, text_size=8, figsize=(8,8))

N-D Ogdoad / Hebdomekontany¶

Ogdoad N-D¶

7D ogdoad—each spoke is an orthogonal axis.

print('GENERATING GEOMETRY: Ogdoad N-D')
plot(MasterSet.ogdoad_nd(), figsize=(7,7))
