Rhinoceros (abbreviated Rhino) is a commercial 3D computer graphics and computer-aided design (CAD) application software developed by Robert McNeel & Associates, a privately held, employee-owned company that was founded in 1980. Rhinoceros is based on NURBS mathematical model, which focuses on producing mathematically precise representation of curves and freeform surfaces in computer graphics (as opposed to polygon mesh).

Rhinoceros is used in processes of computer-aided design (CAD), computer-aided manufacturing (CAM), rapid prototyping and reverse engineering in industries including architecture, industrial design (e.g. automotive design, watercraft design), product design (e.g. jewelry design) as well as for multimedia and graphic design.[1]

Rhinoceros is developed for Microsoft Windows operating system and a beta version is available for OS X.[2] A visual scripting language add-on for Rhino, Grasshopper, is developed by Robert McNeel & Associates.

Features[edit]

Rhinoceros has a scripting language based on Visual Basic, an SDK, and a plug-in system. One plug-in, a parametric modeling tool called Grasshopper, attracted some architects to the program.[3]

File format[edit]

The Rhino file format (.3DM) is useful for the exchange of NURBS geometry. The Rhino developers started the openNURBS Initiative to provide computer graphics software developers 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). The McNeel Wiki has more current information.

Rhinoceros supports the following CAD and image file formats natively (without use of external plugins): DWG/DXF(AutoCAD 200x, 14, 13, and 12 ), SAT (ACIS, export only), Microstation DGN, Direct X (X file format), FBX, X_T (Parasolid, export only), 3DS, LWO, STL, SLC, OBJ, AI, RIB, POV, UDO, VRML, BMP, TGA, CSV (export properties and hydrostatics), uncompressed TIFF, STEP, VDA, GHS, GTS, KML, PLY, Google Sketch-UP. IGES (Alias, Ashlar Vellum, AutoFORM, AutoShip, Breault, CADCEUS, CAMSoft, CATIA, Cosmos, Delcam, EdgeCAM, FastSurf, FastSHIP, Integrity Ware, IronCAD, LUSAS, Maya, MAX 3.0, MasterCAM, ME30, Mechanical Desktop, Microstation, NuGraf, OptiCAD, Pro/E, SDRC I-DEAS, Softimage, Solid Edge, SolidWorks, SUM3D, SURFCAM, TeKSoft, Unigraphics), NASA GridTool, Yamaha ESPRi and Tebis.[4] DWF and DWFx file formats (from Autodesk products) are not supported.

When opening CAD file formats not in Rhino native file format, the program will always create a new drawing called "Untitled" and convert the file, meaning that for the file to remain in its old file format it must be re-converted to its original format. Images cannot be opened directly: they can be inserted as a background bitmap (for sketching), as a wallpaper or used as texture in an object material.

As the AutoDesk AutoCAD's file format changes every new version released (see DWG file format for more information), the Open Design Alliance has to reverse engineer the file format once more. So programs like Rhino3D can't always open AutoCAD files written in the most recent versions.

Rhino3D version 4.0 SR9 opens only DWG/DXF file formats until 2007 version. DWG files from 2008 to 2012 can opened only after being converted to older DWG versions using an appropriate version of Autodesk AutoCAD or the free Autodesk DWG TrueView 2012.
