A path animation moves a point in space along a predefined path (see property Path). The animation path is a spline-based curve consisting of several path keys (also known as 'key frames'). A path key defines a point in space. The parameter of a path key is the animation time - the time at which the point on the path is reached. A path key also defines the type of interpolation that is used for the segment between the current and the next path key. All relevant types of spline-based interpolations can be used for the path segments.

Duration: A path animation, by default, runs from the start (parameter = 0) until the last path key is reached. The parameter of the last path key determines the natural duration of the animation. The optional properties StartParameter and EndParameter can be used to explicitly define which part of the path should be played.

Loop Behavior: When the StartParameter is less than the parameter of the first path key or EndParameter is greater than the parameter of the last path key then the path is automatically repeated using a certain loop behavior. The loop behavior can be defined using the properties PreLoop and PostLoop of the Path.

Important: The path animation requires that the path keys are sorted ascending by their parameter (time value). The method Sort can be called to sort all path keys.
