IsoView

IsoView is a nice simple VTK-based visualization program written by John Shalf (jshalf@ncsa.uiuc.edu).
It can display live isosurface data streamed from a running Cactus simulation. The isosurface geometry data computed in parallel by thorn CactusPUGHIO/Isosurfacer in Cactus and then sent via sockets to any remote IsoView client.

Usage is very easy: you start off the program with the appropriate hostname/port number information addressing a running Cactus job:

IsoView -h <hostname to connect to>
        -cp <control port>
        -dp <data port>

Then, with the mouse buttons in the vizualization window, you can rotate the isosurface, move it, zoom in and out. There are also slider bars to set the isosurface value and colors.

Downloading

You can get the IsoView sources via anonymous checkout from the Cactus cvs server:

cvs -d :pserver: anon@cvs.cactuscode.org:/cactus checkout VizTools/IsoView [ Password is 'anon' ]

and build it on your own (you will need a VTK and FLTK installation for that).

You can also download precompiled IsoView binaries here for Linux x86 and SGI (n32).
