Amira -a Highly Interactive System for Visual Data Analysis

Summary: Amira - a Highly Interactive System
for Visual Data Analysis

1 Introduction
What characteristics should a good visualization system hold? What kinds of data should it
support? What capabilities should it provide? Of course, the answers depend on the particular
task and application. For some users a visualization system may be nothing more than a simple
image viewer or plotting program. For others it is integrated software dedicated to their personal
field of work, such as a computer algebra program or a finite-element simulation system. While
in such integrated systems visualization is usually just an add-on, there are also many specialized
systems whose primary focus is upon visualization itself.
On the one hand, there are many self-contained special-purpose programs written for partic-
ular applications. Examples include flow visualization systems, finite-element post-processors,
and volume rendering software for medical images. On the other hand, several general-purpose
visualization systems have been developed since scientific visualization became an independent
field of research in the late 1980s. These systems are not targeted to a particular application area,
but provide many different modules which can be combined in numerous ways, often adhering
to the data-flow principle and providing means for `visual programming' [23, 4, 17, 1, 5, 15, 7].
In these ways, custom pipelines can be built to solve specific visualization problems. Al-
