# SetStereoViewMatrix(StereoscopicEye, Matrix4x4)

> Sets a custom view matrix for a specific stereoscopic eye.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public void SetStereoViewMatrix(Camera.StereoscopicEye eye, Matrix4x4 matrix)
```

### Parameters

**** (\[StereoscopicEye]\(/engine/6000.7/script-reference/unityengine/camera/stereoscopiceye)): Specifies the stereoscopic view matrix to set.**** (\[Matrix4x4]\(/engine/6000.7/script-reference/unityengine/matrix4x4)): The matrix to be set.

### Remarks

In general, you should use the view matrices provided by the [XRDisplaySubsystem](/engine/6000.7/script-reference/unityengine/xr/xrdisplaysubsystem.md) for accurate stereoscopic rendering. However, when needed for specific scenarios, you can override the view matrices to achieve specific effects. For example, you would need to set custom projection and view matrices to implement binoculars in VR.

When you set custom view matrices, the Camera analyzes them to determine whether it is safe to use a single cull pass or if it must separately cull each eye. Use [Camera.areVRStereoViewMatricesWithinSingleCullTolerance](/engine/6000.7/script-reference/unityengine/camera/arevrstereoviewmatriceswithinsingleculltolerance.md) to find out which will be used.

Call [Camera.ResetStereoViewMatrices](/engine/6000.7/script-reference/unityengine/camera/resetstereoviewmatrices.md) to revert the camera back to using the view matrices provided by the [XRDisplaySubsystem](/engine/6000.7/script-reference/unityengine/xr/xrdisplaysubsystem.md). Note that the [Camera.stereoSeparation](/engine/6000.7/script-reference/unityengine/camera/stereoseparation.md) is not applied until you call [Camera.ResetStereoViewMatrices](/engine/6000.7/script-reference/unityengine/camera/resetstereoviewmatrices.md).

### Examples

```csharp
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    // Use this for initialization
    void Start()
    {
    }

    // Update is called once per frame
    void Update()
    {
        Camera cam = GetComponent<Camera>();

        Matrix4x4 viewL = cam.worldToCameraMatrix;
        Matrix4x4 viewR = cam.worldToCameraMatrix;

        viewL[12] += 0.011f;
        viewR[12] -= 0.011f;
        cam.SetStereoViewMatrix(Camera.StereoscopicEye.Left, viewL);
        cam.SetStereoViewMatrix(Camera.StereoscopicEye.Right, viewR);
    }
}
