API Reference > geometry-core > CartesianGeometry > GeodesicPathPoint > evaluateNewtonFunction evaluateNewtonFunction MethodStatic Evaluate the newton function and derivatives: (UAB cross UCB) dot d1cross with as the central data, UAB = vector from pointA to pointB, UCB = vector from pointC to pointA. Return order is: values[0] = the function values[1] = derivative wrt pointA.phi values[2] = derivative wrt pointB.phi values[3] = derivative wrt pointC.phi evaluateNewtonFunction(pointA: GeodesicPathPoint, pointB: GeodesicPathPoint, pointC: GeodesicPathPoint, values: Float64Array): void Parameter Type Description pointA GeodesicPathPoint pointB GeodesicPathPoint pointC GeodesicPathPoint values Float64Array Returns - void Defined in geometry3d/Ellipsoid.ts Line 993 Last Updated: 12 June, 2024
