Show : show the rays

Hide : hide the rays

Close : hide the rays and close the utility

There could be an huge number of rays. Several ways to reduce the number of rays to display :

If the energy ratio between a ray and the strongest ray is lower than the energy range, then this ray will not be plotted.

It is possible to modify the contributions. Only the selected contributions will be displayed. If nothing is modified, the selection is supposed to be the same than for the computation (default). If the selection includes contributions that weren't selected for the computation, these contributions will be ignored.

If the button Define an observation direction/point isn't checked, then the rays for all the observations will be plotted. It is also possible to select a particular observation direction or observation point :
