The project was started as a hobby by Don Burns in 1998, as means of porting a hang gliding simulator written on top of the
Peformer scene graph running on IRIX to what was then a humble Linux PC. In mid 1999, Robert Osfield began helping out with
Performer scene graph running on IRIX to what was then a humble Linux PC. In 1999, Robert Osfield began helping out with
the simulator development and ported the scene graph element to Windows. In september 1999 the source code was open sourced,
and the openscenegraph.org website was born, with Robert taking over as project lead and Don remaining focused on the hang
gliding simulator. In April 2001, in response to growing interest in the project around the world, Robert went fulltime
on the project, setting up OpenSceneGraph Professional Services,
