The void <http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a01593.html#a306a73ea16dfe10406725cefb3867dfa> get <http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00648.html#a341e0295def3df6e07a014a1ff8195b4> (Matrixd <http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00489.html> &matrix) const method lets you convert a Quat to a 4x4 Matrix. void <http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a01593.html#a306a73ea16dfe10406725cefb3867dfa> decompose <http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00489.html#a3aad163d793a9d5af248e42fd2e94dea> (osg::Vec3d <http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00972.html> &translation, osg::Quat <http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00648.html> &rotation, osg::Vec3d <http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00972.html> &scale <http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00489.html#a9a9ad7cd3f007df5f559e10d471f1981> , osg::Quat <http://trac.openscenegraph.org/documentation/OpenSceneGraphReferenceDocs/a00648.html> &so) const decompose the matrix into translation, rotation, scale and scale orientation. Will extract the trans, rot and scale components out of the matrix.
