Hi Verdavine, The svn/trunk version of the OSG has a new osgVolume::MultiPassTechnique that supports mixing 3D geometries with ray traced volumes. This technique requires you to decorate the scene with a the new osgVolume::VolumeScene node, and then attach the MultiPassTechnique to the VolumeTile's. The two new classes work together to manage a multipass rendering technique that renders the main 3d scene to a depth and colour buffer, then uses this way doing the volume ray tracing. The new technique also allows you to provide a manifold geometry mesh to constrain the rendering to just the area within that geometry.
