Methods

Name	Description
ApproximateLength(BezierCurve)	Calculate the approximate length of a BezierCurve. This is less accurate than CalculateLength(BezierCurve, int), but can be significantly faster. Use this when accuracy is not paramount and the curve control points are changing frequently.
CalculateCurveLengths(BezierCurve, DistanceToInterpolation[])	Populate a pre-allocated lookupTable array with distance to 't' values. The number of table entries is dependent on the size of the passed lookupTable.
CalculateLength(BezierCurve, int)	Calculate the length of a BezierCurve by unrolling the curve into linear segments and summing the lengths of the lines. This is equivalent to accessing GetCurveLength(int).
EvaluateAcceleration(BezierCurve, float)	Given a Bezier curve, return an interpolated acceleration at ratio t.
EvaluateCurvature(BezierCurve, float)	Given a Bezier curve, return an interpolated curvature at ratio t.
EvaluatePosition(BezierCurve, float)	Given a Bezier curve, return an interpolated position at ratio t.
EvaluateTangent(BezierCurve, float)	Given a Bezier curve, return an interpolated tangent at ratio t.
GetDistanceToInterpolation(BezierCurve, float)	Gets the normalized interpolation, (t), that corresponds to a distance on a BezierCurve.
GetDistanceToInterpolation<T>(T, float)	Return the normalized interpolation (t) corresponding to a distance on a BezierCurve. This method accepts a look-up table (referred to in code with acronym "LUT") that may be constructed using CalculateCurveLengths(BezierCurve, DistanceToInterpolation[]). The built-in Spline class implementations (Spline and NativeSpline) cache these look-up tables internally.
GetNearestPoint(BezierCurve, Ray, int)	Gets the point on a BezierCurve nearest to a ray.
GetNearestPoint(BezierCurve, Ray, out float3, out float, int)	Gets the point on a BezierCurve nearest to a ray.
Split(BezierCurve, float, out BezierCurve, out BezierCurve)	Decompose a curve into two smaller curves matching the source curve.
