Our project is an application that simulates cities before implementation. Using AR technology, our application makes a city with the finest details: you can add trees, factories, agricultural lands, and comprehensive infrastructure. The app will visualize the city, and analyze how “green” it is. For illustration, how the city manages wastes, CO2 emissions, natural catastrophes, and generating electricity. The application designs a model of the city evolution, and shows the results of user interface. Simply, you can predict the prosperity in advance of building. That shall enable you to avoid potential risks, and guarantee ideal application in real-life.
