What is 3D modeling? When talking about it, someone may still raise this question even though there are many 3D modeling products all around and people benefit from such a technology in daily life. This article will refer to what 3D modeling is, what it is used for, and how it works, which will help with learning about this technology.


What is 3D Modeling?


To start with, 3D is short for three-dimensional, which is three-dimensional graphics. Applied in computer graphics, 3D modeling is a kind of technology to produce 3D digital representations of any object or surface. Generally speaking, it is to use 3D production software to create a model with 3D data through virtual 3D space.


How does 3D Modeling Work?

In the virtual space, some dots called vertices are manipulated to link each other in a polygon shape(usually a triangle or a quadrilateral) and form a mesh, the core of the 3D model, which acts as the object surface and can be changed by adjusting the position of vertices. Every vertex has its coordinate data so the location of each vertical and horizontal point can be identified by the software.

With these vertices, artists are enabled to create their various works. When the works are displayed on the computer screen, the different gray levels of color make the human eye produce a visual illusion, and the 2D computer screen is perceived as a 3D image looking realistic.


What is 3D Modeling Used for?


Maybe we don’t realize it, but 3D modeling is used in many industries, and it is also a dependency for many practitioners in creative careers, such as architects, game designers and animators. The following part will introduce several common uses of 3D modeling.


  • Architecture

It’s very common to apply 3D modeling in architecture. Both outdoor design and interior design are inseparable from it. 3D renderings produced through modeling can be displayed to convey design concepts and ideas in great detail, enabling stakeholders to foresee the architecture work. In addition, potential problems can be easily seen, which is conducive to the refinement of the whole project.


  • Game design

3D modeling is widely applied in game development, so there are 3D games that many people are familiar with, like World Warcraft and Heroes of the Storm. It creates characters, props, scenes, basic terrain, and so on, which realizes a vivid and realistic world for players. Building immersive experiences, 3D games succeed in engaging players and thriving.


  • 3D printing

Another popular application for 3D modeling is 3D printing, ranging from the auto industry to the medical field. For sure, the scope of its application will be wider and wider in the future. Differentiating from general printing, 3D printing use metals, ceramics, plastics and other materials instead of ink and paper to turn 3D models into physical objects.


  • Entertainment

The entertainment industry, such as animated films and television shows, is booming today thanks to the development of 3D modeling. At the same time, it is also used in special effects in advertising and other fields, benefiting from its eye-catching effect.


  • Product design

Nowadays there are lots of products involving 3D modeling for the reason that the adoption of it in product design enables designers to pinpoint errors in time and correct them accordingly, reducing the waste of time, manpower and money before the production process. Furthermore, it will have a good effect on presentations to customers or investors, who can envision the product directly.


Types of 3D Modeling Software


Since 3D modeling can achieve such powerful and diverse functions, there must be a variety of 3D software technical support for different purposes. Some excellent software is listed below.


  • Blender

Blender is a free, open-source 3D modeling software offering a range of animation solutions from modeling, animation, textures, and rendering, to audio processing, video editing, and more. It has to be said that it is a great choice for 3D modeling.


  • AutoCAD

As an automatic computer-aided design software, AutoCAD can be used to draw 2D drawings and basic 3D designs. With a wide range of adaptability, it can be run on microcomputers and workstations supported by a variety of operating systems. It is especially popular among architects and engineers.


  • Autodesk Maya

Well-known as the world’s top 3D animation software, Autodesk Maya has an excellent reputation and a high price tag because it features perfect functions, flexible work, extremely high production efficiency and realistic rendering. It’s applied in professional film and television advertising, character animation, special effects, and so on.
