snapxyz - Convert snapshot to xyzc data
snapxyz [parameter=value]
snapxyz converts snapshot data into Position-Color (xyzc) data,
or optionally Position-Velocity-Color (xyzuvwc) data. In this format utilities
exist to interactively browsing this 3D dataset, optionally accompanied
with velocity vectors. See xyzview(1NEMO)
.
The positions are computed using
a bodytrans(3NEMO)
expression, and default to x,y,z for position, and
vx,vy,vz for velocity.
Arguably glnemo2(1NEMO)
is a better way to view
3D snapshot data, though the expression transformation is not something
we can easily do for snapshots.
The following parameters are
recognized in order; they may be given in any order if the keyword is also
given. Use --help to confirm this man page is up to date.
- in=
- Input file of
snapshot(5NEMO)
data. No default.
- out=
- Output file for xyzc/xyzuvwc data
in xyz(3NEMO)
format. No default.
- times=
- Range of times to convert. [Default:
all].
- xvar=
- Expression for x-axis variable [Default: x].
- yvar=
- Expression
for y-axis variable [Default: y].
- zvar=
- Expression for z-axis variable
[Default: z].
- vxvar=
- Expression for vx-axis variable (see also vel= below)
[Default: vx].
- vyvar=
- Expression for vy-axis variable (see also vel= below)
[Default: vy].
- vzvar=
- Expression for vz-axis variable (see also vel= below)
[Default: vz].
- vel=t|f
- Should velocities be output also. Default: t.
- color=
- Expression for point color. This must be an integer expression, 0 being
the background color, 1 and higher some other colors. [Default: 1].
- visib=
- Expression for point visibility. This must be an integer expression, where
0 means invisible, and anything else visible. [Default: 1].
