For the chess and go term, see ply (chess).For the polygon data file format, see PLY (file format).A ply is a strand or layer of material, such as yarn, rope, plastic, wood, or paper. Plywood is so called because it is a laminate of several thin layers of wooden material. Two-ply toilet paper has two separable layers, each about as thick as single-ply, affording greater comfort and convenience without a commensurate increase in the risk of clogging the toilet.

PLY is a computer file format known as the Polygon File Format or the Stanford Triangle Format.The format was principally designed to store three dimensional data from 3D scanners. It supports a relatively simple description of a single object as a list of nominally flat polygons. A variety of properties can be stored including: color and transparency, surface normals, texture coordinates and data confidence values. The format permits one to have different properties for the front and back of a polygon.
