| Abstrakt: | This thesis provides a presentation of a parallel
volume data visualization system for data supplied from confocal
laser scanning microscopy. It describes and compares various
methods for volume visualization and optimalization and their
implementations on parallel architectures. The parallel volume
renderer we have developed is implemented on a 16 nodes PC cluster
connected by a high-speed Myrinet network using MPI, ray-casting
and binary-swap algorithm. To improve efficiency, several
optimalizations for increasing the speed of the ray casting
process are used, including empty regions skipping and an
efficient bricking addressing scheme. We also suggest several
methods of improving the performance when using MPI and compilers.
The system is capable of running interactively (several frames per
second) on a PC
cluster.
