.nodeTypes. X3DFollowerNode

An X3DFollowerNode maintains an internal state that consists of a current value and a destination value. Both values are of the same data type into which the term [S|M]F evaluatesfor a given specialization. It is the 'data type of the node'. In certain cases of usage, the terms input and output fit better for destination value and current value, respectively. Whenever the current value differs from the destination value, the current value gradually changes until it reaches the destination value producing a smooth transition. It generally moves towards the destination value but, if a transition triggered by a prevous destination value is still in progress, it may take a short while until the movement becomes a movement towards the new destination value.
