End-User Visualization Software

? Lots of choices...this is not going to be comprehensive

? Tableau for data visualization (commercial)

? Commercial software often domain specific ?Geology: Eclipse and VIP ?CFD: ANSYS Fluent

? Python tools ?Matplotlib (2D...mostly non-interactive) ?MayaIV (3D)

? Free scientific visualization software ?Paraview ?VisIT

ParaView

? We'll talk about it because I've used it ?...and it's free

?Open-source 3D Sci Vis application ?Created in 2000 ?Built by Kitware, Inc. and Los Alamos National. Lab

? funded by US Department of Energy ? built on VTK ("Visualization Tool Kit") ? available for MS Windows, Linux, OSX ? support for large dataset / distributed architecture

ParaView

? In general, you don't write code ? Just import your data

? Unless your data isn't in a format that Paraview can read ? Then you need to write a script to convert it... ? VTK file format is the native data format of Paraview ? Python is a good choice for the conversion script

? Can also write custom code to run inside Paraview ? Again, in Python....
