NAME

       mcdisplay-webgl-classic - mcstas Graphical display of simulations using WebGL (in a browser)

SYNOPSIS

       mcdisplay-webgl-classic  [-h]  [–default]  [–dirname DIRNAME] [–inspect INSPECT] [–nobrowse] [–invcanvas]
       [–first FIRST] [–last LAST] [-n N] INSTR [options ...]

DESCRIPTION

       The mcdisplay-webgl-classic front-end is a graphical debugging tool.  It presents a schematic drawing  of
       the instrument definition, showing the position of the components and the paths of the simulated neutrons
       through  the  instrument.   It is thus very useful for debugging a simulation, for example to spot compo‐
       nents in the wrong position or to find out where neutrons are getting lost.  To use the  mcdisplay-webgl-
       classic front-end with a simulation, run it as follows: mcdisplay-webgl-classic INSTR args... where INSTR
       is  the  name  of  either the instrument source INSTR.instr or the simulation program INSTR.out generated
       with mcstas, and args are the normal command line arguments for the simulation, as for mcrun.  The -h op‐
       tion will list valid options.

       This is the classic WebGL (browser) plotting tool.

OPTIONS

       INSTR  Displays the given mcstas 3D model with its defaults/current parameters.

       name1=value1 ...
              Displays the given mcstas model with given parameters.

       -h, –help
              show this help message and exit

       –default
              automatically use instrument defaults for simulation run

       –dirname DIRNAME
              output directory name override

       –inspect INSPECT
              display only particle rays reaching this component

       –nobrowse
              do not open a webbrowser viewer

       –invcanvas
              invert canvas background from black to white

       –first FIRST
              zoom range first component

       –last LAST
              zoom range last component

       -n N, –ncount N
              Number of particles to simulate
