Information about 3DM and OBJ file formats

Name 3DM OBJ
Full name Rhino 3D Model OBJ geometry format
File extension .3dm .obj
MIME type text/plain
Developed by Robert McNeel & Associates Wavefront Technologies
Type of format
Description The Rhinoceros file format (.3DM) is useful for the exchange of NURBS geometry. The Rhino developers started the openNURBS Initiative to provide computer graphics software developers with the tools to accurately transfer 3-D geometry between applications. An open-source toolkit, openNURBS includes the 3DM file format specification, documentation, C++ source code libraries, and .NET 2.0 assemblies to read and write the file format on supported platforms (Windows, Windows x64, Mac, and Linux). 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 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.
