Struct 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"Namespace: UnityEngine.Splines
Syntax
public struct SplineComputeBufferScope<T> : IDisposable where T : ISplineType Parameters
| Name | Description |
|---|---|
| T | The type of spline. |
Constructors
SplineComputeBufferScope(T)
Create a new SplineComputeBufferScope.
Declaration
public SplineComputeBufferScope(T spline)Parameters
| Type | Name | Description |
|---|---|---|
| T | spline | The spline to create GPU data for. |
Properties
CurveLengths
A ComputeBuffer containing the cached length of all spline curves.
Declaration
public readonly ComputeBuffer CurveLengths { get; }Property Value
| Type | Description |
|---|---|
| ComputeBuffer |
Curves
A ComputeBuffer containing BezierCurve.
Declaration
public readonly ComputeBuffer Curves { get; }Property Value
| Type | Description |
|---|---|
| ComputeBuffer |
Info
Returns a SplineInfo Vector4.
Declaration
public readonly Vector4 Info { get; }Property Value
| Type | Description |
|---|---|
| Vector4 |
Methods
Bind(ComputeShader, Int32, String, String, String)
Set up a shader with all of the necessary ComputeBuffer and Spline metadata for working with functions found in Spline.cginc.
Declaration
public void Bind(ComputeShader shader, int kernel, string info, string curves, string lengths)Parameters
| Type | Name | Description |
|---|---|---|
| ComputeShader | shader | The compute shader to bind. |
| Int32 | kernel | The kernel to target. |
| String | info | The float4 (typedef to SplineData in Spline.cginc) Spline info. |
| String | curves | A StructuredBuffer{BezierCurve} or RWStructuredBuffer{BezierCurve}. |
| String | lengths | A StructuredBuffer{float} or RWStructuredBuffer{float}. |
Dispose()
Free resources allocated by this object.
Declaration
public void Dispose()Upload()
Copy Spline curve, info, and length caches to their GPU buffers.
Declaration
public void Upload()
