Method GetDistanceToInterpolation

GetDistanceToInterpolation(BezierCurve, float)

Gets the normalized interpolation, (t), that corresponds to a distance on a BezierCurve.

Declaration

public static float GetDistanceToInterpolation(BezierCurve curve, float distance)

Parameters

Type	Name	Description
BezierCurve	curve	The BezierCurve to calculate the distance to interpolation ratio for.
float	distance	The curve-relative distance to convert to an interpolation ratio (also referred to as 't').

Returns

Type	Description
float	Returns the normalized interpolation ratio associated to distance on the designated curve.

Remarks

It is inefficient to call this method frequently. For better performance create a DistanceToInterpolation cache with CalculateCurveLengths(BezierCurve, DistanceToInterpolation[]) and use the overload of this method which accepts a lookup table.

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.

Declaration

public static float GetDistanceToInterpolation<T>(T lut, float distance) where T : IReadOnlyList<DistanceToInterpolation>

Parameters

Type	Name	Description
T	lut	A look-up table of distance to 't' values. See CalculateCurveLengths(BezierCurve, DistanceToInterpolation[]) for creating this collection.
float	distance	The curve-relative distance to convert to an interpolation ratio (also referred to as 't').

Returns

Type	Description
float	The normalized interpolation ratio associated to distance on the designated curve.

Type Parameters

Name	Description
T	The collection type.
