Spiral Polyskelion

Spiral Types:

(1) Archimedean spiral: r(θ) = a*θ

(1 < number of spiral turns < 2)

(2 < number of spiral turns < 3)

(2) Fermat's spiral (Parabolic spiral): r(θ) = a*sqrt(θ)

(1 < number of spiral turns < 2)

(2 < number of spiral turns < 3)

(3) Hyperbolic spiral (Reciprocal spiral): r(θ) = a/θ

(4) Lituus: r(θ) = a/sqrt(θ)

(5) Logarithmic spiral: r(θ) = a*exp(b*θ)

(b = 0.25)

(b = 0.618)
