Three-dimensional (3D) modeling refers to the creation of a digital representation of a real object. With 3D modeling computer software, users can recreate life-like models on screen. This highly specialized software uses mathematics to create a series of points, lines, and shapes that map out an object’s surface, which ultimately renders a three-dimensional image. Images can be manipulated and refined to look as true to life as desired. 3D modeling allows artists and other professionals to recreate existing objects or build brand new worlds, such as in video games or other media.

3D modeling is utilized in a wide range of industries, including video game development, animation, marketing, manufacturing, architecture, engineering, and geology. One of the earlier 3D modeling software programs, CAD, is still commonly used by engineers, builders, and manufacturers to produce digital production plans. More recently, such professions have been able to turn 3D modeled images into 3D-printed products! 3D modeling often gets associated with entertainment — as animated cartoons, movies, and video games become more realistic. In the advertising and marketing world, artists may use 3D modeling to create prototype images of new or redesigned products.
