Information about PLY and STL file formats

🔸 File format PLY STL
🔸 Full name Polygon File Format Stereolithography File Format
🔸 File extension .ply .stl
🔸 MIME type text/plain model/stl, model/x.stl-ascii, model/x.stl-binary
🔸 Developed by Greg Turk, Stanford University 3D Systems
🔸 Type of format
🔸 Description PLY is a computer file format known as the Polygon File Format or the Stanford Triangle Format. It was principally designed to store three-dimensional data from 3D scanners. The data storage format supports a relatively simple description of a single object as a list of nominally flat polygons. Various properties can be stored, including color and transparency, surface normals, texture coordinates, and data confidence values. In addition, the format permits one to have different properties for the front and back of a polygon. There are two versions of the file format, one in ASCII, the other in binary. STL is a file format native to the stereolithography CAD software created by 3D Systems. Many other software packages support this file format. It is widely used for rapid prototyping, 3D printing, and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without representing color, texture, or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common since they are more compact.
🔸 Technical details Files are organized as a header that specifies the mesh elements and their types, followed by the list of elements itself. The elements are usually vertices and faces but may include other entities such as edges, samples of range maps, and triangle strips. The header of both ASCII and binary files is ASCII text. Only the numerical data that follows the header is different between the two versions. The header always starts with a "magic number", a line containing "ply", which identifies the file as a PLY file. An STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. All STL coordinates were required to be positive numbers in the original specification, but this restriction is no longer enforced, and negative coordinates are commonly encountered in STL files today. As a result, STL files contain no scale information, and the units are arbitrary.
