One of the bottle necks is visualisation of such large datasets.
Although we
use commercial visualisation software such as Enight which is capable of
parallel rendering and processing of data we are looking into alternative
solutions.
Does anyone know if it is possible to perform parallel rendering using the
J3D API?
We've been prototyping in this space recently. Are you using VTK at all
to help with visualizations? Our tact is to work on X3D exporters for
alot of different visualization structures/packages. Then allow the
underlying renderer(currently Java3D and Aviatrix3d) to optimize it.
Aviatrix3d is specifically being designed for this task. Java3D scales
somewhat but its performance on SGI's boxes was disappointing(but
perhaps unimportant in the future). Mostly I see people gearing towards
linux/pc clusters to run these visualizations.
By exporting to X3D you will have a data format to hold your
visualization in a 3D form. Then different X3D engines can optimize the
content for different devices. Currently Xj3D(our X3D engine) supports
rendering on standard PCs and Elumens Dome devices(small domes up to
planetariums) and will shortly have CAVE capabilities. On the other
extreme you might want to view a small subset of a mobile device, say in
the field where the engineering work is being done.
I'd be curious to know the software packages you are using for
simulation, and whether the results are available in XML. Converting
from a XML format into X3D is fairly easy.
