Abstract: A method for digitally processing data representing a three-dimensional volumetric scene, the method being implemented by a computer and comprising the steps of: accessing the data representing the scene; designating a first frame associated with a first mesh; designating a first position in the first mesh; determining a first facet of the first mesh on which the first position is located; accessing a list of pre-established associations between original positions of vertices of the first facet and respective associated positions that are expressed in a reference frame which is specific to a second mesh of a second frame and has a different topology from the first mesh, these associations representing the evolution of the scene over time; and determining, on the basis of the respective associated positions, a position located in the second mesh that is associated with the position designated in the first mesh.
