> Hi All
>
> I have implemented BRLCAD, which is a CSG based ray tracing api, into an
> Openscenegraph application.  I am currently displaying BRLCAD models in the
> Openscenegraph world by generating a "point cloud" using the native BRLCAD
> ray tracer and rendering that as Osg point geometry.
>
> I would like to display these BRLCAD models by ray trace in Openscenegraph
> (yes, it will be slow!).  I have done some searches through the archives
> and have not found a lot of info.  It appears that I am going to have to
> use glReadPixels and glWritePixels prior to the swapbuffers (I am not using
> osgViewer yet).  Does anyone know of a better method to render via ray
> trace in Openscenegraph?
>
> Thanks
