TYPE: SOP
TITLE: Visibility SOP

The Visibility operation is used to hide and expose primitives in the 2D (UV)
and 3D viewports.

Parameters:

    Group                - The primitives to hide or expose.

    Action               - Either "Hide Primitives" or
                           "Expose Primitives".                          /action

    Apply to             - If set to "Selected Primitives" the primitives in
                           the group field are hidden or exposed.  If set to
                           "Non-Selected Primitives" all primitives except
                           those in the group field are hidden or
                           exposed.                                     /applyto

    Viewport             - Either "3D Viewport" or
                           "2D (UV) Viewport".                         /viewport

    Apply Cumulatively   - If this option is enabled, Visibility will append
                           to the visibility information in the input geometry.
                           For example, if primitive 2 was hidden in the
                           input geometry and this primitive is to hide
                           primitive 5, then both primitives 2 and 5 will
                           be hidden in the output.  If this option is
                           disabled then only primitive 5 will be hidden
                           in the output.                            /cumulative
