Great project! We also create simulators. You can watch this video: www.youtube.com/watch?v=jLRHiklQFv8 (starting at 4 minutes 30 seconds)
What do you think about the publication of such projects on the page http://www.openscenegraph.org/projects/osg/wiki/Screenshots/ ? 2011/4/20 Paul Martz <pma...@skew-matrix.com>: > Hi J-S -- It looks great.
