    I am new in brlcad.
    I am trying to follow the cup tutorial

    But when I run the last command to raytracer the cup.
    I get the following error message.

    rt -F:1 -s 512

      Hola Paco,

      You should try the tutorial on the website at http://brlcad.org under Documentation as it's more up to date.  The detail that is causing problems, though, is the -F:1 option.  Remove it (just run "rt" or "rt -F/dev/X" instead).

      Cheers!
      Sean
