A face is an elementary surface geometry. Faces are used in 3D modelling to define meshes

A face is an elementary surface geometry. A face is defined by three (sometimes four) vertices or the indices from a vertices array or collection. Faces are used in 3D modelling, for example to define faceted boundary representations.

Note: Use this tag for questions related to face geometries, do not use this tag for questions related to face recognition (use face-recognition instead).
