Struct SplineSlice<T>

SplineSlice represents a partial or complete range of curves from another Spline. A SplineSlice<T> by itself does not store any BezierKnots. It stores a reference to a separate Spline, then retrieves knots by iterating the SplineRange. Use SplineSlice<T> in conjunction with SplinePath to create seamless paths from discrete Spline segments.

Syntax

public struct SplineSlice<T> : ISpline, IReadOnlyList<BezierKnot>, IReadOnlyCollection<BezierKnot>, IEnumerable<BezierKnot>, IEnumerable where T : ISpline

Type Parameters

Name	Description
T	The type of spline that this slice represents.

Remarks

Iterating a SplineSlice<T> is not as efficient as iterating a Spline or NativeSpline because it does not cache any information. Where performance is a concern, create a new Spline or NativeSpline from the SplineSlice<T>.

Constructors

Name	Description
SplineSlice(T, SplineRange)	Constructor for a new SplineSlice.
SplineSlice(T, SplineRange, float4x4)	Constructor for a new SplineSlice.

Fields

Name	Description
Range	An inclusive start index, number of indices, and direction to iterate.
Spline	The Spline that this Slice will read BezierKnot and BezierCurve data from. A SplineSlice<T> by itself does not store any BezierKnots. Instead, it references a partial or complete range of existing Splines.
Transform	A transform matrix to be applied to the spline knots and tangents.

Properties

Name	Description
Closed	Whether the spline is open (has a start and end point) or closed (forms an unbroken loop).
Count	Return the number of knots in this branch. This function clamps the Range to the Count of the the referenced Spline.
this[int]	Get a BezierKnot at the zero-based index of this SplineSlice<T>.

Methods

Name	Description
GetCurve(int)	Get a BezierCurve from a knot index.
GetCurveInterpolation(int, float)	Return the normalized interpolation (t) corresponding to a distance on a BezierCurve.
GetCurveLength(int)	Return the length of a curve.
GetCurveUpVector(int, float)	Return the up vector for a t ratio on the curve.
GetEnumerator()	Get an enumerator that iterates through the BezierKnot collection. Note that this will either increment or decrement indices depending on the value of the Direction.
GetLength()	Return the sum of all curve lengths.
