Class Spline
A wrapper on top of 
Inheritance
Namespace: UnityEngine.Rendering.PostProcessing
Syntax
[Serializable]
public sealed class Spline
Constructors
Spline(AnimationCurve, Single, Boolean, Vector2)
Creates a new spline.
Declaration
public Spline(AnimationCurve curve, float zeroValue, bool loop, Vector2 bounds)
Parameters
| Type | Name | Description | 
|---|---|---|
| AnimationCurve | curve | The animation curve to base this spline off  | 
| System.Single | zeroValue | The value to return when the curve has no keyframe  | 
| System.Boolean | loop | Should this curve loop?  | 
| Vector2 | bounds | The curve bounds  | 
Fields
cachedData
An array holding pre-computed curve values.
Declaration
public float[] cachedData
Field Value
| Type | Description | 
|---|---|
| System.Single[] | 
curve
The underlying animation curve instance.
Declaration
public AnimationCurve curve
Field Value
| Type | Description | 
|---|---|
| AnimationCurve | 
k_Precision
Precision of the curve.
Declaration
public const int k_Precision = 128
Field Value
| Type | Description | 
|---|---|
| System.Int32 | 
k_Step
The inverse of the precision of the curve.
Declaration
public const float k_Step = 0.0078125F
Field Value
| Type | Description | 
|---|---|
| System.Single | 
Methods
Cache(Int32)
Caches the curve data at a given frame. The curve data will only be cached once per frame.
Declaration
public void Cache(int frame)
Parameters
| Type | Name | Description | 
|---|---|---|
| System.Int32 | frame | A frame number  | 
Evaluate(Single)
Evaluates the curve at a point in time.
Declaration
public float Evaluate(float t)
Parameters
| Type | Name | Description | 
|---|---|---|
| System.Single | t | The time to evaluate  | 
Returns
| Type | Description | 
|---|---|
| System.Single | The value of the curve at time   | 
Remarks
Calling the length getter on a curve is expensive to it's better to cache its length and call Evaluate(Single, Int32) instead of getting the length for every call.
Evaluate(Single, Int32)
Evaluates the curve at a point in time.
Declaration
public float Evaluate(float t, int length)
Parameters
| Type | Name | Description | 
|---|---|---|
| System.Single | t | The time to evaluate  | 
| System.Int32 | length | The number of keyframes in the curve  | 
Returns
| Type | Description | 
|---|---|
| System.Single | The value of the curve at time   | 
GetHashCode()
Returns the computed hash code for this parameter.
Declaration
public override int GetHashCode()
Returns
| Type | Description | 
|---|---|
| System.Int32 | A computed hash code  |
