<p>Techniques for processing scenes of arbitrary complexity comprising a number of objects represented by models. Techniques are provided for building a representation in memory that stores information or represents the inter and intra-model memory dependencies between the various inputs and outputs of the models included in a scene. The memory representation is built based upon intra-model dependencies information (804) and cues information (808) for the scene. In one embodiment, the memory representation is a graph (802) comprising a number of nodes and directed links between the nodes. The nodes in the graph represent (are proxies for) inputs and outputs of the models involved in the scene. The directed links between the nodes represent the intra- and inter-model dependencies between the inputs and outputs.</p>
