IntegratedSpiralTypeName Type

IntegratedSpiralTypeName = "clothoid" | "bloss" | "biquadratic" | "cosine" | "sine"

This is the set of valid type names for "integrated" spirals

• Behavior is expressed by a NormalizedTransition snap function.
• The snap function varies smoothly from f(0)=0 to f(1)=1
• The various snap functions are:
  • clothoid: linear
  • biquadratic: 2 quadratics pieced together, joining with 1st derivative continuity at f(0.) = 0.5, with zero slope f'(0)=0 and f'(1)= 0
  • bloss: A single cubic with zero slope at 0 and 1
  • cosine: half of a cosine wave, centered around 0.5
  • sine: full period of a sine wave added to the line f(u)=u
