The research on Streamed Photon Mapping method has shown its efficiency and potential. Significant caustic effects without an additional caustic map are its undeniable advantage. The method assumed that light spreads in a vacuum; however, such approach excluded the visualization of such phenomena as fog, smoke, or clouds. This paper presents a modification of the basic method of rendering with the help of photon streams, taking into account the simulation of light in dense mediums. The specifics of stream structure and the applied solutions allow to eliminate multiple assessment of the same photons as it occurred in the case of standard Volumetric Photon Mapping.
