Hey Daniel, thanks for your help. I have played a bit more with the rotation option and I think I might have identified the issue… When I set the origin of the rotation in the x menu, and plot only particles, everything works as intended (i.e. if I put the origin in the centre of a box, all 4 pi are filled). However, if I render the plot (e.g. using rho), then only a small fraction of the plot is filled (i.e. I see the box from some distance away). If instead I reverse the sign of the origin in the x menu (i.e. I set it to -0.5,-0.5,-0.5 in a box running from 0 to 1 in all dimensions), then I get a nice 4pi plot again…
So, it might be possible that there’s a sign error somewhere in the routine, when rendering is used… I’d try to dig deeper into the code, but my fortran is horrible :-) Anyway, thanks again for the help! Again, the 4pi option is very nice!
