3D modeling is the process of creating three-dimensional representations of an object or surface using specialized software. During the 3D modeling process, an objects size, shape, and texture can be determined by working with points, lines, and polygons to create 3D shapes within the software. 3D models are essentially made up of vertices, which come together to form a mesh and act as the core of the 3D model. The process of 3D modeling can be done manually, algorithmically, or by scanning.

3D modeling is used in various industries such as film, animation, gaming, interior design, architecture, product design, and manufacturing, among others. In the film and gaming industries, 3D models are used to create characters, settings, props, and entire worlds within video games. In the manufacturing industry, 3D modeling is used to develop prototypes, visualize product ideas, and simulate functionality pre-production. 3D models are also used in the medical industry to create interactive representations of anatomy.

The 3D modeling process produces a digital object capable of being fully animated, making it an essential process for character animation and special effects. 3D models can be purchased from online marketplaces and printed by individuals or companies using commercially available 3D printers, enabling the home-production of objects such as spare parts and even medical equipment.

In summary, 3D modeling is the process of creating three-dimensional representations of an object or surface using specialized software, and it is used in various industries such as film, animation, gaming, interior design, architecture, product design, and manufacturing, among others.
