In this chapter, we explore the performance of the volume rendering methods introduced in Chapter 1 and Chapter 1. We shall analyze the volume rendering on several fronts. First, we examine the speed at which the volume rendering runs. Second, we analyze the accuracy of the volume rendering. That is, we determine how closely our approximations compute the actual volume rendering integrals specified by our model. Third, we examine what effect cell boundaries have on the approximation. We compute the ray integrals over a cell boundary where the color should be consistent and look for variations and discontinuities in the output color that make errors more noticeable.
