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.
The following parameters are recognized
in any order if the keyword is also given:
- 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].
