Blender is a free and open-source 3D computer graphics software product used for creating animated films, visual effects, interactive 3D applications or video games. wikipedia.org

ZBrush is a digital sculpting tool that combines 3D/2.5D modeling, texturing and painting. It uses a proprietary "pixol" technology (see below) which stores lighting, color, material, and depth information for all objects on the screen. wikipedia.org

3D modeling (also known as meshing) is the process of developing a mathematical representation of any three-dimensional surface of object (either inanimate or living) via specialized software. wikipedia.org

3D computer graphics are works of graphic art that were created with the aid of digital computer and specialized 3D software. In general, the term may also refer to the process of creating such graphics, or the field of study of 3D computer graphic techniques and its related technology. wikipedia.org

3D rendering is the 3D computer graphics process of automatically converting 3D wire frame models into 2D images with 3D photorealistic effects on a computer. wikipedia.org

3D printing is a phrase used to describe the process of creating three dimensional objects from digital file using a materials printer, in a manner similar to printing images on paper. wikipedia.org

3D scanning involves using a 3D scanner to analyze a real-world object or environment to collect data on its shape and possibly its appearance (i.e. color). The collected data can then be used to construct digital three-dimensional models. wikipedia.org

Substance Painter is a 3D painting software allowing users to texture, render and share their work.

Digital sculpting, also known as Sculpt Modeling or 3D Sculpting, is the use of software that offers tools to push, pull, smooth, grab, pinch or otherwise manipulate a digital object as if it were made of a real-life substance such as clay. wikipedia.org

Augmented reality (AR) is a live, direct or indirect, view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data. wikipedia.org

Virtual reality replicates an environment that simulates a physical presence in places in the real world or an imagined world, allowing the user to interact with that world. wikipedia.org
