arcBallCamera was deprecated in builds 2022.20160+. It was superseded by the modern Palette:cameraViewport COMP, available in the Palette.

The arcBallCamera can be used to interactively control a camera's position around a scene. The actual functional parts are provided packaged in a complete render setup to better illustrate its usage. You can copy the Camera COMP cam1 out of this component and use it in your own render scene or use this as a default interactive render setup. All parameters described here are located on the actual Camera COMP. The camera can be rotated (lclick), dollied (mclick) and translated (rclick).

The camera's extension Methods can be used to save and recall camera positions.

When placing the camera in your own scene, make sure that the referenced Panel Component has its Mouse UV Buttons parameters for Left, Middle and Right mouse button enabled.
