Cities around the globe are challenged by the ever-growing quantity of urban citizens in order to ensure sustainable urban development. Modeling cities and other urban spaces seems like a complex task for computer graphics, computer vision, and visualization. However, understanding, describing, and modeling the geometry and behavior of cities are significant challenges that ultimately benefit urban planning, mapping and visualization, emergency response, etc. Using interactive modeling to assist in the design and visualization of complex 3D city models is vital. So what exactly is 3D modeling?
In theory, 3D modeling is the process of developing a mathematical representation of any three-dimensional surface of an object via specialized software. The product is called a 3D model. It can be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. Understanding, describing, and modeling the geometry (2D/3D models) of cities are of significant challenge that ultimately leads to a lot of benefits. Using 3D modeling can help cities become smarter, improve environmental performance, transportation and utility networks, and the impact of construction and maintenance. With intelligent 3D model-based design software, you can make informed decisions for a smarter, more sustainable world.
Speaking of smart cities, let’s explore the kind of the 3D solutions that are out there. Esri has recently unveiled Esri CityEngine 2016. The new 3D modeling technology (integrated with ArcGIS online) allows GIS professionals, 3D artists, architects, and urban planners to create smart 3D city models in a matter of minutes. How is the tool helping the concept of smart cities. Let’s check out for ourselves.
- The new Get Map Data interface imports satellite imagery, 3D terrain, and street data from any city in the world.
- This was once a very complicated and time-intensive process and can be done quickly and simply now.
- CityEngine scenes can be published directly on the web for sharing 3D models, analysis results, or design proposals with decision makers or the
As long as we are discussing 3D for smart cities, let’s check out an example closer to home. India’s TATA Consulting Engineers Limited has delivered an elaborate infrastructure project using Autodesk solutions. Delhi – Mumbai Industrial Corridor (DMIC) is India’s most ambitious of $90 billion with the financial & technical aids from Japan, covering an overall length of 1483 KMs between the political capital and the business capital of India, i.e. Delhi and Mumbai. The project aims to develop new industrial smart cities.
Autodesk’s integration of 3D design with GIS helped TCE to build, maintain, and operate its infrastructure, as well as the capabilities of InfraWorks allowed TCE to collaborate with partners for improved delivery of projects.
- AutoCAD Map 3D was used to create contour maps to analyze 3D terrain and the information for entire smart city project.
- Using AutoCAD Civil 3D watershed, analysis is being performed on the surface to analyze the surface watersheds and floodplain mapping.
- Engineers used AutoCAD Civil 3D to build 3D models of roadway corridor of around 180 kms.
- Using Autodesk Naviswork’s clash detection capabilities helped in discovering hundreds of problems that wouldn’t have been visible with traditional 2D tools.
