API Reference > geometry-core > Curve > IntegratedSpiralTypeName IntegratedSpiralTypeName Type alias 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 IntegratedSpiralTypeName = "clothoid" | "bloss" | "biquadratic" | "cosine" | "sine" Defined in curve/spiral/TransitionSpiral3d.ts Line 30 Last Updated: 12 June, 2024
