Future Work

We would like to adopt other volume rendering algorithms to body centered cubic grids and see how they perform. As the bcc grid actually consists of two Cartesian grids which are shifted with respect to each other, it should be possible to design a shear-warp algorithm for bcc grids. For the same reason it should be possible to accelerate volume rendering by the use of graphics hardware.

It would also be necessary to come up with a ray-casting algorithm. For this purpose it would be interesting to investigate the effects of interpolating within bcc grids. Therefore, we would like to adopt the filter analysis and design method of Möller et al. [13] to bcc grids. Since each sampling point in a bcc grid has eight nearest neighbors (as opposed to a Cartesian grid), spherically symmetric filters deserve a more thorough investigation.
