3D

3D (three-dimensional) refers to objects or spaces that have width, height, and depth, giving them a volume and making them appear more realistic compared to two-dimensional (2D) representations. The concept of 3D is widely used in various fields such as computer graphics, animation, printing, cinematography, and virtual reality.

Applications of 3D

Computer Graphics

In computer graphics, 3D modeling is the process of developing a mathematical representation of any three-dimensional surface of an object via specialized software. The product is called a 3D model. These models are used in a variety of industries, including video games, film, architecture, and engineering.

Animation

3D animation involves creating moving pictures in a three-dimensional digital environment. This is done by sequencing consecutive images, or "frames," that simulate motion by displaying them in rapid succession. Popular 3D animation software includes Maya, Blender, and 3ds Max.

3D Printing

3D printing, also known as additive manufacturing, is a process of making three-dimensional solid objects from a digital file. The creation of a 3D-printed object is achieved using additive processes, where an object is created by laying down successive layers of material until the object is complete.

Cinematography

In cinematography, 3D films are motion pictures that enhance the illusion of depth perception, hence adding a third dimension. This is achieved through various techniques such as stereoscopic photography, multi-view capture, or 2D to 3D conversion.

Virtual Reality

Virtual reality (VR) is a simulated experience that can be similar to or completely different from the real world. VR applications include entertainment (e.g., video games), education (e.g., medical or military training), and business (e.g., virtual meetings).
