Swii2, a HTML5/WebGL Application for Cellular Automata Debris Flows Simulation

摘要

We here present the preliminary release of Swii2, a web application for debris flows simulation. The core of the system is SciddicarkO, the latest release of the Sciddica debris flow Cellular Automata family, already successfully applied to the 1997 Albano lake (Italy) debris flow. In Swii2, the Sciddica-kO model runs server-side, while a Web 2.0 application controls the simulation. The graphical user interface is based on HTML5 and JavaScript, which permits to have a fully portable application. The client is able to control the basic SciddicarkO simulation functionalities thanks to asynchronous callbacks to the server. Simulation results are visualized in real time by means of a 3D interactive visualization system based on WebGL, a cross-platform application program interface used to create 3D graphics in Web browsers. Eventually, user-oriented cooperative services, which desktop applications in general do not offer, are conjectured and discussed.
