Free and open-source graphics API From Wikipedia, the free encyclopedia
Coin3D is a free and open-source implementation (library) of the Open Inventor API. Coin3D was originally developed and maintained as commercial software by the Norwegian company Kongsberg Oil & Gas Technologies (formerly Kongsberg SIM).[1] Coin3D, like Open Inventor, is a C++ object-oriented retained mode 3D graphics API used to provide a higher layer of programming for OpenGL. The API provides a number of common graphics rendering constructs to developers such as scene graphs to accomplish this. Coin3D is fully compatible with the Open Inventor API version 2.1.[1] Coin3D can be used to drive advanced visualization solutions in a wide range of application domains such as geo-modelling, CAD, medical visualization, robotics and presentation.

According to Kongsberg Oil & Gas Technologies, the software is used in a number of commercial and open-source, scientific visualization or 3D modeling projects such as OpenRAVE. Apple, for example, used Coin for 3D rendering in iWork '08 and later. FreeCAD relies on Coin3D for visualization.[2][3]
From 1998 to 2011 Coin3D was developed and maintained by Systems in Motion (SIM), later renamed to Kongsberg SIM, later merged into the parent company Kongsberg Oil & Gas Technologies Kongsberg Gruppen. During this period Coin3D was available under a dual license scheme: GPL or a proprietary commercial license. Mid-2011, Kongsberg decided to end Coin3D as a commercial product due to diminishing demand and changing business focus. As a service to the user community Kongsberg re-licensed Coin3D under the less restrictive BSD 3-clause license.[1][4][5] Since then, the BSD licensed source code has been maintained by its users and is available at GitHub.[1]
Several libraries exist that are designed to integrate Coin3D with GUI development environments.
Legacy GUI bindings are Qt (SoQt), Win32 API (SoWin) and Motif (SoXt) are also maintained.
Coin3D is written in C++, but can be accessed from other programming languages using available bindings. Bindings have been developed for Python Pivy, Java and JavaScript.
