||In volumetric visualization, the body centered grid and its
reciprocal, the face centered cubic grid, are despite their good
sampling properties underrepresented regarding available rendering
software and tools.
Described in this thesis is the development of an extension for the
volume rendering engine Voreen implementing two recently presented GPU
accelerated reconstruction algorithms for these grids, along with a
simple nearest neighbor filter. The performance and rendering quality
of the new raycasters is measured and compared to Voreen's existing
Cartesian cubic ray caster.
The results show that rendering of data in the body centered and face
centered cubic format using the new raycasters is possible at
interactive frame rates while maintaining comparable visual quality,
using consumer grade graphics cards.
The goal is for the produced software to be useful for efficiently
visualizing results from experiments with the BCC and FCC grids and
thus help make such data easier to observe.
