Classes

CurveUtility

A collection of methods for extracting information about BezierCurve types.

Wrapper for accessing a SplineData<T> value stored on Spline through one of the embedded key value collections. It is not required to use this class to access embedded SplineData<T>, however it does provide some convenient functionality for working with this data in the Inspector.

EmbeddedSplineDataFieldsAttribute

Attribute used to make an EmbeddedSplineData variable show in the Inspector with a filtered set of fields editable. Use this in situations where you want to specify EmbeddedSplineData parameters in code and not allow them to be modified in the Inspector. to a ISplineContainer.

InterpolatorUtility

InterpolatorUtility provides easy access to all the different IInterpolator implementations.

KnotLinkCollection

A collection of KnotLinks to track how spline knots are linked and the utilities to update these links when splines are modified.

Spline

The Spline class is a collection of BezierKnot, the closed/open state, and editing representation.

SplineAnimate

A component to animate an object along a spline.

SplineComponent

Base class for SplineInstantiate and SplineExtrude, contains common elements to both of these Components

SplineContainer

A component that holds a Spline object.

SplineData<T>

The SplineData{T} class is used to store information relative to a Spline without coupling data directly to the Spline class. SplineData can store any type of data, and provides options for how to index DataPoints.

SplineExtrude

A component for creating a tube mesh from a Spline at runtime.

SplineFactory

Methods to create spline shapes.

SplineIndexAttribute

Attribute used to make an integer variable show in the Inspector as a popup menu with spline choices relative to a ISplineContainer.

SplineInstantiate

SplineInstantiate is used to automatically instantiate prefabs or objects along a spline.

SplineJobs

The SplineJobs class contains utility methods for evaluating spline data using the Jobs system.

SplineMath

Assorted utility functions for math equations commonly used when working with Splines.

SplineMesh

Utility methods for creating and working with meshes.

SplinePath

The SplinePath type is an implementation of ISpline that is composed of multiple sections of other splines (see SplineSlice<T>). This is useful when you want to evaluate a path that follows multiple splines, typically in the case where splines share linked knots.

SplinePath<T>

SplineUtility

A collection of methods for extracting information about Spline types.

Structs

BezierCurve

Control points for a cubic Bezier curve.

Points P0 through P3 are in sequential order, describing the starting point, second, third, and ending controls for a cubic Bezier curve.

BezierKnot

This struct contains position and tangent data for a knot. The position is a scalar point and the tangents are vectors. The Spline class stores a collection of BezierKnot that form a series of connected BezierCurve. Each knot contains a Position, Tangent In, and Tangent Out. When a spline is not closed, the first and last knots will contain an extraneous tangent (in and out, respectively).

DataPoint<TDataType>

A pair containing an interpolation ratio and {TDataType} value.

DistanceToInterpolation

A key-value pair associating a distance to interpolation ratio ('t') value. This is used when evaluating Spline attributes to ensure uniform distribution of sampling points.

GetPosition

Provides methods to calculate, in parallel, the positions along NativeSpline.

GetPositionTangentNormal

A job struct for calculating in parallel the position, tangent, and normal (up) vectors along a NativeSpline.

NativeSpline

A read-only representation of Spline that is optimized for efficient access and queries. NativeSpline can be constructed with a spline and Transform. If a transform is applied, all values will be relative to the transformed knot positions.

SplineComputeBufferScope<T>

SplineComputeBufferScope is a convenient way to extract from a spline the information necessary to evaluate spline values in a ComputeShader. To access Spline evaluation methods in a shader, include the "Splines.cginc" file:

#include "Packages/com.unity.splines/Shader/Spline.cginc"

SplineInfo

SplineInfo is used to wrap a reference to the SplineContainer and index within that container to describe a Spline.

SplineInstantiate.InstantiableItem

Describe the item prefab to instantiate and associate it with a probability

SplineKnotIndex

Provides a tuple to define a couple (Spline index, Knot index) that identifies a particular knot on a spline. This tuple is used by KnotLinkCollection to maintain links between knots.

SplineRange

Describes a subset of knot indices in a Spline. The range might iterate in either the forward or backward direction.

SplineRange.SplineRangeEnumerator

A struct for iterating a SplineRange.

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.

Interfaces

IDataPoint

Defines an interpolation ratio 't' for a Data Point.

IHasEmptyCurves

This interface defines a collection of knot indices that should be considered disconnected from the following knot indices when creating a BezierCurve.

IInterpolator<T>

To calculate a value at some distance along a spline, interpolation is required. The IInterpolator interface allows you to define how data is interpreted given a start value, end value, and normalized interpolation value (commonly referred to as 't').

ISpline

ISpline defines the interface from which Spline types inherit.

ISplineContainer

An interface that represents ISplineContainer on a MonoBehaviour to enable Spline tools in the Editor.

SplineMesh.ISplineVertexData

Interface for Spline mesh vertex data. Implement this interface if you are extruding custom mesh data and do not want to use the vertex layout provided by SplineMesh."/>.
