# IntegrationContext

> Container for integration-specific data and state shared across multiple light transport calculations.

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine.LightTransport](/engine/6000.5/script-reference/unityengine/lighttransport.md)
* **Assembly:** UnityEditor.CoreModule
* **Implements:** [IDisposable](https://learn.microsoft.com/dotnet/api/system.idisposable)

```csharp
public class IntegrationContext : IDisposable
```

## Remarks

This class contains persistent data that can be shared among different invocations of light transport integrators. It serves as a container for cached computations, acceleration structures, and other data that can be reused to improve performance across multiple integration passes.

**Usage Notes:**

* Most user code will not need to create IntegrationContext objects directly.
* Contexts are typically managed by [IWorld](/engine/6000.5/script-reference/unityengine/lighttransport/iworld.md) implementations.
* Manual context creation is only needed for advanced integration scenarios.

Reusing an IntegrationContext across multiple integrator operations can significantly improve performance by avoiding redundant preprocessing and data structure rebuilding.
