Volume raycasting techniques are important Abstract for both visual arts and
visualization. They allow an efficient generation of visual effects and
the visualization of scientific data obtained by tomography or numerical
simulation. Thanks to their flexibility, experts agree that GPU-based
raycasting is the state-of-the art technique for interactive volume rendering.
It will most likely replace existing slice-based techniques in the near
future. Volume rendering techniques are also effective for the direct rendering
of implicit surfaces used for soft body animation and constructive
solid geometry.
