abstract = "It is well known in the signal-processing community that the
Body-Centered Cubic grid is the optimal sampling grid in 3D.
In volume visualization, the Cartesian grid is by far the
most popular type of grid because it is convenient to
handle. But it requires 29.3% more samples than the
Body-Centered Cubic grid. In order to convince people used
to Cartesian grids for years of the advantages of
Body-Centered Cubic grids, we must prove their usability in
many different volume rendering algorithms. Further we have
to show that we get a performance gain without or with only
slight loss of image quality compared to Cartesian grids.
Therefore we introduce several practical reconstruction
schemes on Body-Centered Cubic grids, which are very general
and can be used in a number of applications and tasks.
Together with the development of powerful and flexible
consumer graphics hardware, interactive hardware-accelerated
volume rendering algorithms gain popularity. Rendering
performance becomes a big issue, which can be a strong
argument in favour of Body-Centered Cubic grids. We adapted
some of the most popular volume rendering approaches
exploiting hardwareacceleration to Body-Centered Cubic
grids: both 2D and 3D texture-based volume rendering and the
projected tetrahedra algorithm. At least partly we succeeded
in achieving a performance gain on our new grid and further
produced some impressive rendering results comparable to the
Cartesian grid version.",
