General overview

In these pages we describe how to use the SIMPLE development environment to build a virtual universe and couple it to a GAMA model.

The development environment is made up of two distinct parts designed to work together: a plugin for GAMA (Unity plugin) and a package for Unity.

The GAMA plugin integrates new agent types and a new type of experimentation, making it easy to link with Unity. It also includes tools for automatically generating a VR version of an existing GAMA model.

The Unity package includes a set of prefabs that make it easy to build a virtual environment and link it to GAMA. It also includes tools for automatically importing and exporting geometries from/to GAMA.

For the installation of the Unity plugin for GAMA, see here. For the installation of the SIMPLE Unity template, see here

Tutorial

We offer a complete tutorial to illustrate how to build a complete virtual environment with interactions from an existing GAMA model. In this tutorial, we start with the traffic model included in the GAMA model library. In this model, vehicles (car) travel on a road network from building to building. The greater the number of vehicles on a road relative to its capacity, the slower the vehicles will move along the road. In addition, each vehicle emits pollutants into the air. The VR version we propose in this tutorial allows you to navigate with a manager's view of the world and to close/open roads.
