This paper presents a procedural city modeling method that generates realistic, scalable cities from terrain input using agent-based simulation, focusing on land use and building distribution to produce plausible urban environments.

Contribution

It introduces a novel agent-based approach that captures developmental behaviors, enabling automatic and customizable city generation from minimal input.

Findings

Produces convincing city models with realistic land use and building distribution.

Supports transition from villages to metropolises in generated cities.

Allows artistic customization through adjustable parameters.

Abstract

We propose a method to procedurally generate a familiar yet complex human artifact: the city. We are not trying to reproduce existing cities, but to generate artificial cities that are convincing and plausible by capturing developmental behavior. In addition, our results are meant to build upon themselves, such that they ought to look compelling at any point along the transition from village to metropolis. Our approach largely focuses upon land usage and building distribution for creating realistic city environments, whereas previous attempts at city modeling have mainly focused on populating road networks. Finally, we want our model to be self automated to the point that the only necessary input is a terrain description, but other high-level and low-level parameters can be specified to support artistic contributions. With the aid of agent based simulation we are generating a system of agents and behaviors that interact with one another through their effects upon a simulated environment. Our philosophy is that as each agent follows a simple behavioral rule set, a more complex behavior will tend to emerge out of the interactions between the agents and their differing rule sets. By confining our model to a set of simple rules for each class of agents, we hope to make our model extendible not only in regard to the types of structures that are produced, but also in describing the social and cultural influences prevalent in all cities
