                         outer integrals in the volume rendering equation. We report a set

                         efficiency of our proposal against Riemann summation with uniform 
                         step size. The comparisons are made for both CPU and GPU 
                         implementations and show that our method delivers both accuracy 
                         control and competitive performance.",
