mcdisplay - mcstas Graphical display of simulations

mcdisplay [-h] [–default] [–dirname DIRNAME] [–inspect INSPECT] [–invcanvas] [-n N] INSTR [options ...]

The mcdisplay 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 components in the wrong position or to find out where neutrons are getting lost. To use the mcdisplay front-end with a simulation, run it as follows: mcdisplay 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 option will list valid options.

The default plotting backend is mcdisplay-pyqtgraph, but there exists a number of additional plotters such as mcdisplay-matplotlib, mcdisplay-webgl-classic (using WebGL), mcdisplay-webgl (using WebGL and NodeJS), mcdisplay-matlab (using Matlab or Octave). This is the PyQtGraph plotting tool.
