Modern GPUs are powerful enough to enable interactive display of high-quality
volume data even despite the fact that many volume rendering methods do not
present a natural fit for current GPU hardware. However, there still is a
vast amount of computational power that remains unused due to the inefficient
use of the available hardware. In this work, we demonstrate how advanced
scheduling methods can be employed to implement volume rendering algorithms
in a way that better utilizes the GPU by example of three different
state-of-the-art volume rendering techniques.
