3D model Design
In 3D computer graphics, 3D modeling is the process of developing a mathematical representation of any surface of an object (either inanimate or living) in three dimensions via specialized software. The product is called a 3D model. Someone who works with 3D models may be referred to as a 3D artist. It can be displayed as a two-dimensional image through a process called 3D rendering or used in a computer simulation of physical phenomena. The model can also be physically created using 3D printing devices.
Models may be created automatically or manually. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting.
3D modeling software is a class of 3D computer graphics software used to produce 3D models. Individual programs of this class are called modeling applications or modelers.
Three-dimensional (3D) models represent a physical body using a collection of points in 3D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc. Being a collection of data (points and other information), 3D models can be created by hand, algorithmically (procedural modeling), or scanned. Their surfaces may be further defined with texture mapping.
3D models are widely used anywhere in 3D graphics and CAD. Their use predates the widespread use of 3D graphics on personal computers. Many computer games used pre-rendered images of 3D models as sprites before computers could render them in real-time. The designer can then see the model in various directions and views, this can help the designer see if the object is created as intended to compared to their original vision. Seeing the design this way can help the designer/company figure out changes or improvements needed to the product.
Today, 3D models are used in a wide variety of fields. The medical industry uses detailed models of organs; these may be created with multiple 2-D image slices from an MRI or CT scan. The movie industry uses them as characters and objects for animated and real-life motion pictures. The video game industry uses them as assets for computer and video games. The science sector uses them as highly detailed models of chemical compounds. The architecture industry uses them to demonstrate proposed buildings and landscapes in lieu of traditional, physical architectural models. The engineering community uses them as designs of new devices, vehicles and structures as well as a host of other uses. In recent decades the earth science community has started to construct 3D geological models as a standard practice. 3D models can also be the basis for physical devices that are built with 3D printers or CNC machines.

F.A.Q about 3D model Design
What Is 3D Modeling?
3D modeling is the process of creating a 3D representation of any surface or object by manipulating polygons, edges, and vertices in simulated 3D space. You've seen the results of 3D modeling in movies, animations, and video games that are filled with fantastical and imaginative creatures and structures.
3D modeling can be achieved manually with specialized 3D production software that lets an artist create and deform polygonal surfaces or by scanning real-world objects into a set of data points that can be used to represent the object digitally.
How 3D modeling is used
3D modeling is used in a wide range of fields, including engineering, architecture, entertainment, film, special effects, game development, and commercial advertising.
A popular example of 3D technology is its use in major motion pictures. Just think of the scenery "Avatar," the 2009 movie from director James Cameron. The film helped to transform the 3D industry when it used many of the concepts of 3D modeling to create the movie's planet Pandora.
The learning curve
3D modeling is fun but difficult. Unlike many graphic arts fields, 3D modeling has a substantial learning curve and involves mastering sophisticated software. Beginners in 3D can be put off by the time needed to learn 3D modeling, but, with patience, they can create animations, structural renderings, and video game graphics.
The software you choose to use will likely have a wealth of online tutorials and instructional classes. Take advantage of these resources to help you become proficient with the software and 3D modeling.
3D modeling software
3D modeling software allows you to design basic 3D models of characters or objects. Full-featured programs provide the tools you need to flesh out your designs with realistic details.
