Construct an Nbody snapshot with particles distributed according to the density profile, constructed either from parameters passed as command-line arguments, or as an INI file with all required parameters, or as a text file with potential coefficients (*.coef_bse, *.coef_bsec, *.coef_spl, *.coef_cyl or *.mass for BSE, BSECompact, Spline, CylSpline and Spherical, correspondingly). Particles are given zero velocity and thus the snapshot is not an equilibrium model.

char const* description

Initial value:

=
    "renderdensity:  create an nbody snapshot with rendering of a given density profile with a set of particles at rest.\n"
    "The density is specified either as command-line arguments, or as an input file.\n"
    "  In the first case the following arguments are possible:\n"
    "density=???     name of the density model\n"
    "mass=1          total mass\n"
    "q=1             axis ratio y/x\n"
    "p=1             axis ratio z/x\n"
    "scalerad=1      scale radius of the model (another spelling is rscale)\n"
    "scalerad2=1     second scale radius (if applicable)\n"
    "gamma=1         power-law index of the density cusp\n"
    "sersicindex=4   shape parameter of the Sersic profile\n"
    "  In the second case, only one argument is necessary:\n"
    "file=???        input text-file with potential parameters (*.ini), coefficients (*.coef_*), or spherical mass profile (*.mass)\n"
    "  Output the rendered density profile into the file specified by the following parameters:\n"
    "out=???         output snapshot\n"
    "nbody=???       number of points in snapshot\n"
    "outformat=Text  output format (Text/Nemo/Gadget)\n"
