In this paper we propose an alternative approach to create animations in X3D. This approach allows extended flexibility to control animations during run-time. Among the extended features, it is possible to: control the speed of the animation; play the animation backwards; repeat any specific time interval of the animation and access any key-frame instantly. In order to illustrate this we propose a new node called TimeClock node. This node implements the same functionalities of a TimeSensor node but with the ability to independently set the time frame, overcoming current X3D limitations in the time model specification for creating animation with interpolators. We think this approach is useful for both animators, developers and users: animators can carefully analyze on the fly their work, users can easily control an animation using a DVD like interface and developers do not need to worry about creating several different interpolators for the same animation. We present our current results along with some examples of usage.
