💀Annotation of Skeleton object

Object annotation involves selecting points from a list by their type and placing them at desired locations on the object. The sequence of points is connected by a line, forming a skeleton graph.

You can move a point individually or all points of the object together. In case the required point is not visible on the object, its setting can be skipped and the graph will be disconnected.
The corresponding buttons are provided to indicate the degree of overlapping of points.

The Interpolation function reduces the time it takes to annotate objects in video clips by working between skeleton keyframes. Changing any skeleton point creates a keyframe for the entire object, so all points must be corrected at once on the keyframe.
