How to calculate the points
let the number of points n ∈ ℕ
thus each point i = { ½, 1½, …, n-½ }
lies in a spherical coordinate system pᵢ = ( r, θ, φ ) ] ∀ i
at the constant radius r
the polar angle θ = arccos( 2 ( i / n ) - 1 )
and the azimuthal angle φ = i · ϕ
with the golden ratio Φ = ( √ ̅5 + 1 ) / 2
and the golden angle ϕ = 2π / Φ²
