Procedural Content Graphs for Urban Modeling

Figure 5

Encapsulation of a graph that extends the “fit-to-scope” operation to lists. The thick-line ports indicate the gates of the graph, which are mapped to the encapsulated node’s ports. Graph parameters are also mapped to the node’s parameters. The supergraph uses this encapsulated graph to easily copy and fit a brick rooftop into each cell of a rectangular grid (both brick and grid are also encapsulations). The result is a detailed roof surface.
