Architecture Fiction: Pixel City - Procedurally generated city

Beyond the Beyond (Bruce Sterling) reports on Architecture Fiction: Pixel City - Procedurally generated city. I want to live here.


Some literature on procedurally generated networks (this city seems to be on a grid):

  • Guoning Chen, Gregory Esch, Peter Wonka, Pascal Mu ̈ller, Eugene Zhang (2008) "Interactive Procedural Street Modeling"

    This paper addresses the problem of interactively modeling large street networks. We introduce an intuitive and flexible modeling framework in which a user can create a street network from scratch or modify an existing street network. This is achieved through designing an underlying tensor field and editing the graph representing the street network. The framework is intuitive because it uses tensor fields to guide the generation of a street network. The framework is flexible because it allows the user to combine var- ious global and local modeling operations such as brush strokes, smoothing, constraints, noise and rotation fields. Our results will show street networks and three-dimensional urban geometry of high visual quality.

    Urban simulation models and their visualization are used to help regional planning agencies evaluate alternative transportation investments, land use regulations, and environmental protection policies. Typical urban simulations provide spatially distributed data about a number of inhabitants, land prices, traffic, and other variables. In this article, we build on a synergy of urban simulation, urban visualization, and computer graphics to automatically infer an urban layout for any time step of the simulation sequence. In addition to standard visualization tools, our method gathers data of the original street network, parcels, and aerial imagery and uses the available simulation results to infer changes to the original urban layout. Our method produces a new and plausible layout for the simulation results. In contrast with previous work, our approach automatically updates the layout based on changes in the simulation data and, thus, can scale to a large simulation over many years. The method in this article offers a substantial step forward in building integrated visualization and behavioral simulation systems for use in community visioning, planning, and policy analysis. We demonstrate our method on several real cases using a 200-Gbyte database for a 16,300-km2 area surrounding Seattle.

    Based on complex network theory, this paper proposes a topological evolution model for urban road network. The model also considers the external factors that affect network growth such as population density and economic index, which makes it flexible to adjust the influencing factors while for different types of networks. Furthermore, it’s feasible
    to visualize the differences with the real data in ArcGIS. Then, a case study of road network in Shanghai Pudong New Area is given, several common indicators are calculated. The results show good agreement between real data and model to verify the model is correct and valid.
