Information about STL and OBJ file formats

Name STL OBJ
Full name Stereolithography File Format OBJ geometry format
File extension .stl .obj
MIME type text/plain
Developed by 3D Systems Wavefront Technologies
Type of format
Description 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. OBJ (or .obj) is a geometry definition file format first developed by Wavefront Technologies for its Advanced Visualizer animation package. The file format is open and has been adopted by other 3D graphics application vendors.
Technical details 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. The OBJ file format is a simple data format that represents 3D geometry alone — namely, the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of vertices, and texture vertices. Vertices are stored in a counter-clockwise order by default, making explicit declaration of face normals unnecessary. OBJ coordinates have no units, but OBJ files can contain scale information in a human-readable comment line.
