In this work we propose an alternative animation approach to the traditional key frame based interpolation model. By way of illustration we propose a set of nodes that apply these principles to the X3D standard. In contrast to predefined key frame animations our way of defining animations allows an application to dynamically respond to the current situation and calculate an animation on the fly, while the content author can work with an extremely simple mental model for the animations. It is also our opinion that the way these nodes calculate an animation creates smooth and thus pleasing transitions. In addition, our node set can be used to approximate the effects of inertia, without the requirement and overhead of a heavy physics engine being present. With only a little of this inertia effect applied, objects (e.g. a slider thumb) can subjectively appear to have more physical substance.
