Avizo (software)
Encyclopedia
Avizo is a general-purpose commercial software application for scientific and industrial data visualization
Data visualization
Data visualization is the study of the visual representation of data, meaning "information that has been abstracted in some schematic form, including attributes or variables for the units of information"....

 and analysis.

Avizo is developed by VSG - Visualization Sciences Group and was originally designed and developed by the Visualization and Data Analysis Group at Zuse Institute Berlin (ZIB) under the name Amira. Avizo was commercially released in November 2007.

Overview

Avizo is a software application which enables users to perform interactive visualization
Interactive visualization
Interactive visualization is a branch of graphic visualization in computer science that involves studying how humans interact with computers to create graphic illustrations of information and how this process can be made more efficient....

 and computation on 3D data sets.
The Avizo interface is modelled on the visual programming. Users manipulate data and module components, organized in an interactive graph representation (called Pool), or in a Tree view
Tree view

. Data and modules can be interactively connected together, and controlled with several parameters, creating a visual processing network whose output is displayed in a 3D viewer.

With this interface, complex data can be interactively explored and analyzed by applying a controlled sequence of computation and display processes resulting into a meaningful visual representation and associated derived data.
