An array of  instances for setting the camera position for each frame. If `null`, the camera position will not change and will remain at the existing position.

#### Examples

For an example that includes this property, see the [Interface IOperationsAnimation](VM.Operations.Post.Interfaces.IOperationsAnimation.md).

#### Remarks

This method records the loaded animation frames to a specified file format. It supports different recording types and range options. The frame rate can be adjusted, and custom camera positions for each frame can be set through the `viewSpecs` parameter.

### <a id="VM_Operations_Post_Interfaces_IOperationsAnimation_SetFollowingCameraTarget_System_String_"></a> SetFollowingCameraTarget(string)

Sets the target body for the camera. The camera's position and orientation will follow those of the target body.

```csharp
void SetFollowingCameraTarget(string targetName)

```

#### Parameters

`targetName` string

The names of the target entity. The target entities are Body, Marker, Node.

#### Examples

For an example that includes this property, see the [Interface IOperationsAnimation](VM.Operations.Post.Interfaces.IOperationsAnimation.md).

#### Remarks

This function allows the camera to track and maintain the same position and orientation as the target body. It is useful for situations where the camera needs to follow an object, such as in a third-person perspective or object tracking scenario. If the target body is a ResultMarker and its `IsVisible` property is `false`, it will automatically be set to `true` to ensure visibility when being tracked by the camera.

### <a id="VM_Operations_Post_Interfaces_IOperationsAnimation_SetViewSpec_VM_Operations_Post_Interfaces_IViewSpec_"></a> SetViewSpec(IViewSpec)

Updates the camera information for the current animation frame position.

```csharp
void SetViewSpec(IViewSpec viewSpec)

```

#### Parameters

`viewSpec` [IViewSpec](VM.Operations.Post.Interfaces.IViewSpec.md)

The  instance containing the new camera information.

#### Examples

For an example that includes this property, see the [Interface IOperationsAnimation](VM.Operations.Post.Interfaces.IOperationsAnimation.md).

#### Remarks

This method updates the camera information for the current position in the animation frames using the provided `viewSpec`.

### <a id="VM_Operations_Post_Interfaces_IOperationsAnimation_ShowAll"></a> ShowAll()

Makes all entities visible in the current view.

```csharp
void ShowAll()

```

#### Examples

For an example that includes this property, see the [Interface IOperationsAnimation](VM.Operations.Post.Interfaces.IOperationsAnimation.md).

#### Remarks

The  method is used to make all entities in the current view visible. This is useful for resetting the view to display all entities after some have been hidden.

### <a id="VM_Operations_Post_Interfaces_IOperationsAnimation_StopAnimation"></a> StopAnimation()

Stops the currently playing animation.

```csharp
void StopAnimation()

```

#### Examples

For an example that includes this property, see the [Interface IOperationsAnimation](VM.Operations.Post.Interfaces.IOperationsAnimation.md).

#### Remarks

This method stops the playback of the animation frames that are currently playing. If no animation is currently playing, the method should handle this scenario appropriately, such as by displaying an error message or logging the issue.
