Name

snapxyz - Convert snapshot to xyzc data

Synopsis

snapxyz [parameter=value]

Description

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.

Parameters

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].
