.PLY File Extension

Three-dimensional image file created using the Polygon File Format, an open standard that describes objects as a collection of polygons; contains a header followed by a list of vertices that specify the shape of each polygon.

PLY files are used by many different 3D programs. They may be saved in either a binary or plain text format.

NOTE: Since the PLY file format was developed at Stanford University, it is also known as the Stanford Triangle Format.
