StarSplatter is a tool for creating images and animations from astrophysical particle simulation data. It treats each particle as a Gaussian ”blob”, with an exponential fall-off similar to the SPH smoothing length or gravitational softening length common in astrophysics simulations. It also properly anti-aliases points, so even if the particles are very small the results may look better than one would get by simply binning particle counts to produce an intensity image.StarSplatter runs under the control of the Tcl scripting language (see also here). This allows it to be easily integrated with other programs; it is also easy to set up scripts to render animations. StarSplatter is designed to work with TIPSY, a package for analyzing particle simulation data.This software was developed at the Pittsburgh Supercomputing Center in association with the Grand Challenge Cosmology Consortium. Funding was provided by the National Science Foundation. (Source:
