An open-source toolkit, openNURBS includes the 3DM file format specification, documentation, C++ source code libraries and. The Rhino developers started the openNURBS Initiative to provide computer graphics software developers the tools to accurately transfer 3-D geometry between applications. The Rhinoceros file format (.3DM) is useful for the exchange of NURBS geometry. A visual scripting language add-on for Rhino, Grasshopper, is developed by Robert McNeel & Associates. Rhinoceros is developed for the Microsoft Windows operating system and OS X.

Rhinoceros is used in processes of computer-aided design (CAD), computer-aided manufacturing (CAM), rapid prototyping, 3D printing and reverse engineering in industries including architecture, industrial design (e.g. Rhinoceros geometry is based on the NURBS mathematical model, which focuses on producing mathematically precise representation of curves and freeform surfaces in computer graphics (as opposed to polygon mesh-based applications). Rhinoceros (typically abbreviated Rhino, or Rhino3D) is a commercial 3D computer graphics and computer-aided design (CAD) application software developed by Robert McNeel & Associates, an American, privately held, employee-owned company founded in 1980.
