curveLengthWithFixedIntervalCountQuadrature Method

Run an integration (with a default Gaussian quadrature) with a fixed fractional step

• This is typically called by specific curve type implementations of curveLengthBetweenFractions.
• For example, in Arc3d implementation of curveLengthBetweenFractions:
  • If the Arc3d is true circular, it the arc is true circular, use the direct arcLength = radius * sweepRadians
  • If the Arc3d is not true circular, call this method with an interval count appropriate to eccentricity and sweepRadians.

curveLengthWithFixedIntervalCountQuadrature(fraction0: number, fraction1: number, numInterval: number, numGauss: number5): number

@returns Returns the curve length via an integral estimated by numerical quadrature between the fractional positions.

Returns - number
