Hallo,
Have a look at osgUtils SceneView and search for this:
/** Callback for overidding the default method for compute the offset
projection and view matrices.*/
struct ComputeStereoMatricesCallback : public osg::Referenced
{
virtual osg::Matrixd computeLeftEyeProjection(const osg::Matrixd&
projection) const = 0;
virtual osg::Matrixd computeLeftEyeView(const osg::Matrixd& view)
const = 0;
virtual osg::Matrixd computeRightEyeProjection(const osg::Matrixd&
projection) const = 0;
virtual osg::Matrixd computeRightEyeView(const osg::Matrixd& view)
const = 0;
};
We subclassed from this and calculated all projections according to the
screen and headtracker informations, which worked fine independent of
the stereomode in use.
Hope this helps
