#### Abstract

Animation of one-to-many phenomena (fractures, tears, breaks, cracks…) is challenging. This article builds over recent works that proposed a 3-stages modelling and simulation pipeline, made of a cascade of models: geometry-free physical model → explicit modelling of the evolving topology → geometrical model. On the Physics’ side, in the framework of masses-interactions network modelling, the article extends the recent Splitting-MAT method, where the physical splits occur onto the material points, toward 3 dimensional volume models. Downstream, it introduces a topo-geometrical pipeline adapted to this upstream split-on-the-masses property. Experiments, and analysis of the complexity of the topo-geometrical part, show that, while offering constructible and manageable means, separating Physical, Topological and Geometrical aspects in the 3-stages pipeline enables a rich variety of one-to-many dynamics, with good efficiency.
