package V3d

        ---Purpose: This package contains the set of commands and services
        --          of the 3D Viewer. It provides a set of high level commands
        --          to control the views and viewing modes. This package is
        --          complementary to the Visual3D graphic package.
        --    Warning
        -- The CSF_WALKTHROUGH variable enables you to
        -- manage the perspective of the view in the viewer by
        -- defining setenv CSF_WALKTHROUGH "Yes".
        -- If you use the syntax unsetenv
        -- CSF_WALKTHROUGH, you undefine the variable
        -- (you make sure that the variable is deactivated). In
        -- this case, the eye is located outside the 3D bounding
        -- box of the view. This is the default behavior for
        -- managing the view perspective.
