 ===== Avizo ===== ===== Avizo =====
 Avizo is a software application which enables users to perform interactive visualization and computation on 3D data sets. The Avizo interface is modelled on visual programming. Users manipulate data and module components, organized in an interactive graph representation (called Pool), or in a 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 in a meaningful visual representation and associated derived data. Avizo is a software application which enables users to perform interactive visualization and computation on 3D data sets.

 ParaView is an open-source, multi-platform scientific data analysis and visualization tool that enables analysis and visualization of extremely large datasets. ParaView is both a general purpose, end-user application with a distributed architecture that can be seamlessly leveraged by your desktop or other remote parallel computing resources and an extensible framework with a collection of tools and libraries for various applications including scripting (using Python), web visualization (through ParaViewWeb), or in-situ analysis (with Catalyst). ParaView leverages parallel data processing and rendering to enable interactive visualization for extremely large datasets. It also includes support for large displays including tiled displays and immersive 3D displays with head tracking and wand control capabilities. ParaView also supports scripting and batch processing using Python. Using included Python modules, you can write scripts that can perform almost all the functionality exposed by the interactive application and much more. ParaView is an open-source, multi-platform scientific data analysis and visualization tool that enables analysis and visualization of extremely large datasets.

 ===== VisIt ===== ===== VisIt =====
 VisIt is a free, open source, platform independent, distributed, parallel, visualization tool for visualizing data defined on two- and three-dimensional structured and unstructured meshes. VisIt’s distributed architecture allows it to leverage both the compute power of a large parallel computer and the graphics acceleration hardware of a local workstation. VisIt’s user interface is often run locally on a Windows, Linux, or macOS desktop computer while its compute engine component runs in parallel on a remote computer. VisIt’s distributed architecture allows VisIt to visualize simulation data where it was generated, eliminating the need to move the data to a visualization server. VisIt can be controlled by its Graphical User Interface (GUI), through the Python and Java programming languages, or from a custom user interface that you develop yourself. More information about VisIt can be found online at [[https://visit.llnl.gov/]]. VisIt is a free, open source, platform independent, distributed, parallel, visualization tool for visualizing data defined on two- and three-dimensional structured and unstructured meshes.
