This is a program for interactive visualisation of Gadget N-body simulation snapshots. It can automatically identify and read all of the formats described in the Gadget-2.0 documentation and produce dot plots (optionally colour coded by particle properties such as temperature, metallicity etc) or SPH smoothed density plots of the particle distribution. It can handle simulations with too many particles to display by random sampling the particles to keep the number displayed roughly constant as the viewpoint is moved around. Other features include the ability to:
The program is written in a mix of C and Fortran so you need working C and Fortran compilers to build it. GTK-2 is required for the GUI. It also has some optional dependencies:
Tar file containing the source code and configure script: gadgetviewer-1.0.7.tar.gz
Durham local users can access the svn repository through the Trac site at https://astro-codes.dur.ac.uk
The tar file contains a README file with instructions for compiling and running the code.
