This is a program for interactive visualisation of

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:

  • Read user defined particle properties from HDF5 or type 2 binary snapshots
  • Select particles by position or by other properties and track them between snapshots
  • Make histograms and scatterplots of particle properties,
    optionally highlighting any selected particles
  • Make simple movies

This program replaces the old IDL version.

The program is written in a mix of C and
