While many wonderful commercial software packages exist for visualising scientific data (such as the widely used Interactive Data Language), I found they were cumbersome for particle-based data. Much of what I wanted to do was specific to SPH, like interpolating to an array of pixels using the kernel. While generic routines exist for such tasks, I could not explain how they worked, and they were slow. Also, while interactive gizmos are handy, it was more difficult to perform the same tasks non-interactively, as required for the production of animations. The major work in the visualisation of SPH data is not the image production itself but the manipulation of data prior to plotting. Much of this manipulation makes sense within an SPH framework.

splash is designed for this specific task - to use SPH tools to analyse SPH data. Publishable images and animations can be obtained efficiently from the raw data with a minimum amount of user effort. The development of powerful visualisation tools has enabled me to pick up on effects present in my simulation results that I would not otherwise have noticed — the difference between a raw particle plot and a rendered image can be substantial. A key goal of splash is to eliminate the use of crap-looking particle plots as a means of representing SPH data.

What it does

splash is a utility for visualisation of output from (astrophysical) simulations using the Smoothed Particle Hydrodynamics (SPH) method in one, two and three dimensions. It is written in modern Fortran and utilises giza, a custom-build backend graphics library to do the actual plotting. The following features are included:

Examples of plots produced with splash can be found in the gallery or by looking at papers with figures produced using splash.

What it doesn’t do

splash is geared towards gas dynamics simulations with SPH and has basically grown out of my visualisation needs. Thus it is not particularly useful for things like water and solids in SPH. An SPH visualisation tool geared towards the non-gaseous side of things you may want to have a look at is pv-meshless, by John Biddiscombe.

splash also doesn’t make coffee.

splash, the paper

The algorithms implemented in splash are not described here, but instead described in a paper [Price07], available from:

This paper should be cited if you use splash for scientific purposes, and please do so as it is my only form of thanks.
