FIGURE 1 Development stages for MMASS platform.
FIGURE 2 MMASS model elements and relationships among them.
FIGURE 3 The structure of the MMASS library.
FIGURE 4 Concerns of the MasManager.
FIGURE 5 A high-level class diagram for the Space package.
FIGURE 6 Regular 5 × 5 toroidal grids with Von Neumann neighborhood (a VonNeumannTorusSpace in the MMASS space package).
FIGURE 7 XML spatial definition and the corresponding graph editing tool.
FIGURE 8 Concrete agents are subclasses of the AbstractAgent class.
FIGURE 9 A single minimum spanning tree allows the diffusion of a field over the space without replications, but a separate structure is needed to compute field intensity in destination sites. The structure size is O(n2).
FIGURE 10 Minimum spanning tree with S as source site.
FIGURE 11 Three minimum spanning trees used for field diffusion, according to the source site (root node of the tree).
FIGURE 12 A sample crowd modeling application of the MMASS platform. On the left, the simulator UI shows the spatial structure of agents' environment. On the right, the final 3D visualization is shown.
FIGURE 13 The interface between the bi-dimensional simulator and an external 3D modeling tool (3D Studio Max) is realized by means of a log file indicating relevant elements of simulation dynamics.
