BSD and Bitbucket? Coin3D used to be a commercial product, right?
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).
During this period Coin3D was available under a dual licensing scheme, offering the choice between GPL or a Professional Edition 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 BSD 3-clause license.
This letter was sent to Professional Edition License holders and the mailing lists in November 2011.
The old web site www.coin3d.org has been shut down, and all requests are redirected to this page.
