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:
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.
