simonekekerg Posted May 11, 2014 Share Posted May 11, 2014 Is it possible to get the distance the current ray has travelled? I'm looking into doing something similar to this: http://magnuswrenninge.com/wp-content/uploads/2010/03/Wrenninge-OzTheGreatAndVolumetric.pdf where they have a nice way of simulating multiple scattering in volumes by varying some parameters along the shadow ray.
