Coin3D

Coin3D is an Open Inventor clone by the Norwegian company Kongsberg Oil & Gas Technologies (formerly Kongsberg SIM). 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. Coin3D is distributed as open source (with ability to purchase commercial developer license) and thus benefiting from a large user base in the open source community while maintaining commercial code quality. Coin3D is being used by many small and large companies to drive advanced visualization solution in a wide range of application domains such as geo-modelling, CAD, medical visualization, robotics and presentation.
