'''3D computer graphics''', sometimes called '''3D computer-generated imagery''' ('''3D-CGI'''), refers to [[computer graphics]] that use a [[three-dimensional]] (3D) representation of geometric data (often [[Cartesian coordinate system#Cartesian coordinates in three dimensions|Cartesian]]) stored in the computer for the purposes of performing calculations and rendering [[digital image]]s, usually [[2D image]]s but sometimes [[3D image]]s. The resulting images may be stored for viewing later (possibly as an [[Computer animation|animation]]) or displayed in [[Real-time computer graphics|real time]].{{cite book |last=Foley |first=James D. |title=Computer Graphics: Principles and Practice |last2=van Dam |first2=Andries |last3=Feiner |first3=Steven K. |last4=Hughes |first4=John F. |publisher=Addison-Wesley |year=2013 |isbn=978-0321399526 |edition=3rd}} |

| ⚫ | Materials and textures are properties that the render engine uses to render the model. One can give the model materials to tell the render engine how to treat light when it hits the surface. Textures are used to give the material color using a color or albedo map, or give the surface features using a [[bump map]] or [[normal mapping|normal map]]. It can be also used to deform the model itself using a [[displacement map]]. |
