# fsMapViewSet3DCustomViewOrientationInRadians<no value>
This function can be used to set a custom view orientation for the MapView camera when in 3D mode.

 

 

##### Syntax

``` wasm
bool fsMapViewSet3DCustomViewOrientationInRadians(
    FsContext ctx,
    FsTextureId id,
    double dPitch,
    double dBank,
    double dHeading
    )
```

| Parameters | Description                                                                                          |
|------------|------------------------------------------------------------------------------------------------------|
| `ctx`      | A value of type `FsContext` provided as an argument of the gauge callback.                           |
| `id`       | The MapView render ID as returned by the function `fsMapViewCreate`.                                 |
| `dPitch`   | The pitch value, in radians, clamped between 0 and 2\(pi\), relative to the aircraft orientation.  |
| `dBank`    | The bank value, in radians, clamped between 0 and 2\(pi\), relative to the aircraft orientation.   |
| `dHeading` | The headingvalue, in radians, clamped between 0 and 2\(pi\), relative to the aircraft orientation. |

##### Return Values

Returns false if:

-   no texture matches the given MapView ID
-   the `ctx` is invalid

Otherwise it will return true.

 

##### Remarks

This function is only valid when `fsMapViewSet3D` is set to true (ie: 3D is enabled), and when the view orientation has been set to use a custom camera using `fsMapViewSet3DViewOrientation`.
