3D modeling is a process of creating a 3D model by using specialized software. It is a method of developing a wireframe model representing a 3 dimensional object. The model is designed and developed by using a set of points in 3D space connected through several geometric figures such as lines and curved surface. Some of the methods for creating a 3D model include polygonal modeling, primitive modeling, splines and patches modeling and non-uniform rational B-spline (NURBS) modeling. 3D mapping technology creates three-dimensional views of different objects on a computer screen. It offers real time viewing experience of a place or thing on a map. 3D mapping is used in many applications across different industry verticals such as construction, transportation, automobile, entertainment and healthcare. In healthcare industry, 3D mapping technology is used to study human anatomy and gives a better view of different parts of the human body. 3D mapping and 3D modeling technology is used in construction industry to create construction schematics and to draw a 3-dimensional view of a building. Designing cars, truck and other vehicles are few applications of 3D mapping and 3D modeling technology in automobile industry.
