Amira is designed for an end-user who has minimal experience
with visualization tools, meaning that anything deemed
untrivial is considered to be too complicated and
should be treated as a bug.
Amira provides a kind of visualization network, which
graphically displays the current settings and relationships
among the visualization components.
In contrast to other tools like AVS or IBM DX, you don't see
a (possibly complicated) data flow diagram, instead the data
is directly displayed
as (green) icons and the appropriate displays
pop up from right-mouse button clicks on the green icons.
Predefined Networks
While it is easy, with only a little experience,
to construct simple visualization
networks from scratch, a couple of
`standard' visualization networks which arise in
every-day work
with Cactus data are predefined. To get a list of all these
(daily growing) list of networks, simply issue
amira2000 '+?'
on the command line. This will print a list of available
networks and, for example, starting Amira with
amira2000 +remoteviz
will launch Amira ready for retrieving data from a
remote simulation.
Working with 3D data
As an example of looking at some data set, for example 3D
data in FlexIO format written by Cactus, simply invoke
Amira with the appropriate filename, e.g.
amira2000 psi0re_3d.ieee
Note that large datasets beyond the 2GB limit are
supported and can be handled, conveniently fast, with
on-demand loading
A green data icon will appear, named according to the
file name.
From that, use the right-mouse button to select a
`timeslice' data set, for which a number of
visualization modules can be applied.
