package Visual3d

    ---Version:

    ---Purpose: This package contains the group of classes necessary
    --      for the implementation of commands for the 3D visualiser.
    --      Use of this package is reserved to the visualiser.
    --
    --      The visualiser manages the structures, the views, the
    --      light sources, and object picking.

    ---Keywords: View, Light, Pick
