12.4.3 Camera key-framing
The current position of a camera can be stored in what is called a viewpoint. Simply select the View Save viewpoint menu item and a new key item will be created in the Model Viewer. As with the View item, selecting a Key item allows you to edit the position and orientation of that stored camera position. In addition, by selecting the View Prev/Next viewpoint, you can smoothly interpolate between camera key positions. This feature comes in handy when recording an animation and different camera positions need to be visited in a repeatable manner. Camera keys are stored in the FEBio Studio session file so they can be retrieved later.
