This article presents a topologically-based animation system which aims at representing the topological evolution of structured ob jects over time. To guarantee robustness and allow versatility, it relies on the n-dimensional generalised map formalism. The animation is modelled as a series of maps which are ordered in time and represent each topological modification of the structure. We then define dedicated topological operations that we resort to in a script to create the animation. We finally show the usefulness of the approach by means of a specific application in geology, namely the representation of a subsoil evolution in 2D.
