15/07/09: v1.12.2 released.
This is a minor release, main things are as follows:- Variable marker sizes implemented, so now it is possible to plot sink particles with size proportional to their radius!
- Dark matter rendering now works with the block-labelled GADGET read.
- VINE read handles star particles.
- Labels for coordinates/vectors are not overridden by default (only if not set or if coordinate system changed).
- A nasty bug with automatic pixel selection getting random pixel numbers and seg faulting fixed.
- Temporary arrays in the main plotting loop are explicitly allocated and deallocated rather than being left to the compiler. Fixes crashes using older versions of ifort.
- Data reads added for snsph, oilonwater.
- Minor bugs fixed with contouring options, cursor positioning, identification of columns in ascii read amongst other things.
20/04/09: v1.12.1 released.
This is a minor release, where the main new things are as follows:- Ability to customise the label on 3D projection plots has been added (so you can now have e.g. "surface density" instead of "column density" if you like).
- Contour levels are set better (and printed).
- Limits for a contour plot can be set independently of a rendered plot of the same quantity.
- Numeric labels can be added to contours.
- SPLASH_HMIN_CODEUNITS environment variable added which can be used to enforce a minimum smoothing length on the particles during rendering.
- Text shapes added via the "annotate plot" option in the le(g)end menu can now be edited interactively. This is a preliminary feature I hope to expand to all text objects.
- All known bugs fixed*.
22/12/08: v1.12.0 released.
The main new things are as follows:- A second quantity can be plotted as contours on top of the rendered quantity (ie. they no longer have to be the same). A contour plot will appear if you turn on the "plot contours" option in the r)ender menu.
- Pressing backspace over annotation in interactive mode deletes it. This is a bit clunky at the moment but improvements are planned. You can also quit interactive mode with 'esc' or 'ctrl-c' as well as the usual 'q'.
- You can now invoke SPLASH from the command line directly, mainly this is so it works better in scripts, but it can also be used as a shortcut. For example to render whatever is in column 6 to the screen, I would use: splash -render 6 -dev /xw where the x (-x) and y (-y) axes can also be specified, and/or a vector plot (-vec) and/or a contour plot (-cont).
- There is now a new "splash calc" utility for calculating global quantities (e.g. energies) as a function of time. Basically I got sick of trying to work out how to read weird formats (sphNG) in my analysis tools in order to just calculate a few things, so I made SPLASH do it. You can also calculate the minimum, mean and maximum of all columns as a function of time, and (because I needed to do it), the mass above a series of density thresholds, also as a function of time. The results are put into plain ascii files and can then be plotted using asplash -e (with the -e option to give the best defaults for this kind of plot). Suggestions on a postcard!
- Can plot the natural log of a quantity.
- All bugs have been fixed*
