RemarksFreeCameraAnimationNode provides logic to animate a FreeCamera's CameraPosition, TargetPosition and UpDirection.
FreeCameraAnimationNode can perform a linear or spherical animation.
When AnimationType is set to LinearInterpolation (by default), then CameraPosition, TargetPosition and UpDirection are animated with moving lineary from one position or vector to another. This means that if you only animate CameraPosition, then the distance to the TargetPosition will change during animation. If you want to circle the camera around the target object and preserve the distance, then use the CameraAnimationNode.
To rotate the camera around TargetPosition, set the AnimationType is set to SphericalInterpolation. In this mode for each KeyFrames in CameraPositionTrack a Quaternion is created from UpDirection and calculated LookDirection. Then CameraPosition and UpDirection are animated using Quaternion.Slerp. In this mode it is also possible to lineary animate the TargetPosition and the distance of the Camera to the TargetPosition.
