Figure 1: This example demonstrates the need for urban ecosystems. The image in a) shows a terrain occupied by a wild ecosystem and
b) displays the same ecosystem grown over the city layout, where the vegetation invades all areas and attempts to fill them entirely and the
ecosystem is chaotic with no control. The image c) shows the managed urban ecosystem that has areas with wild plant growth but also areas
controlled by our plant management system.
We address the open problem of spatial distribution of vegetation
in urban environments by introducing a user-guided simulation and
procedural system for integrating plants into the interactive design
process of 3D urban models. Our approach uses as input 3D ge-
ometry of an urban layout from which it infers initial conditions
and parameters of procedural rules. A level of manageability is cal-
culated for each area of the urban space. The manageability level
defines the amount of influence between the wild ecosystem simu-
lation, where the plants compete for resources and seed freely, and
