uns_2dplot - create a 2D image of an UNS file
uns_2dplot in=uns_file
select=range-or-component [parameter=value] ...
uns_2dplot reads
an UNS snapshot and plot a 2D image of the particles positions. Each particles
are smoothed by a gaussian and colored according to a logscale colormap.
The final effect give the illusion that the object has been colored by
density. The rendering that you get, looks like the one you get with glnemo2(see
man glnemo2) on gas particles.
The computation of all gaussian is multithreaded
and the number of threads used can be selected from the command line.
The
following parameters are recognized.
- in=uns input file
- Currently, the following
input files are supported: Nemo regular, Nemo piped, Gadget3, Gadget2,
Gadget1, Ramses, list of files
- select=select-particles
- Select particles.
Sets of particles must be selected using the : range operator, separated
by a comma. E.g. select=0:9,10:19 would select two sets of 10 particles,
or by component (gas,halo,stars,bulge,disk,bndry) [all]
- prop=roperties
to display (metal,age,temp,rho)
- In case of structured snapshots like Gagdet
or Ramses, you can select the properties you want to display (metal,age,temp,rho).
By default it displays accumulated density of particles in the light of
see.
- psort=sort properties
- sort properties according to 0:none, 1:min, 2:max.
The default is [0] no sorting.
- dev=output-image-file
- you specify here the
output name of the image which will be automatically saved in GIF format.
If you give only the character ’?’, PGPLOT will ask you, interactively, in
which format you would like to save the image [?]
- times=time-range
- Select
time [all]
- range=range-for-all-axis
- give the same range for all x,y and
z axis. [-range:range], default none.
- xrange=x-axis-range
- Range of values
for the X axis, specified with a pair of numbers separated by a
colon. The default range is [-35.0:35.0].
- yrange=y-axis-range
- zrange=z-axis-range
- xy=display-xy-plan?
- select as true if you want to display particles in XY
plan. Default is [t].
- xz=display-xz-plan?
- select as true if you want to display
particles in XZ plan. Default is [t].
- zy=display-zy-plan?
- select as true if
you want to display particles in ZY plan. Default is [f].
- com=center-of-mass?
- center according to center if mass. Default is [t].
- hsml=use hydro smooth
length
- Use hydro smooth length if exists, default [f] false
- cb=toggle color
map
- default is false [f]
- cmap=select color map
- available color maps 0:rainbow,
1:heat, 2:gray, default is [0]
- itf=image transfer function
- image transer
function 0:linear, 1:logarithmic, 2:square-root, default [1]
- sview=single-display-view?
- if true, only one image will be created for all requested plan xy|xz|zy. If
false, and if a name is given to ’dev’ parameter, then a separated gif file
will be created for each plan xy|xz|zy. Default is [t].
- title=image-title
- give
here a title for the image
- pfname=rint-file-name?
- if true, simulation’s filename
will be displayed, default [t]
- no=index-image-offset
- specify the filename
index offset of the image, default [0]
- pixel=gaussian-pixel-size
- size in
pixel of the gaussian [20]
- dimx=internal-width
- internal image width in pixels
[1024]
- dimy=internal-height
- internal image height in pixels [1024]
- gp=gaussian-parameter
- gaussian parameter [5]
- threads=#threads-used
- number threads used for the
computation [2]
- verbose=verbose?
- display some verbose log [f]
