SYNOPSIS

C:

DtObject DoInvisSwitch(switchvalue)
DtSwitch switchvalue;

FORTRAN:

INTEGER∗4 DOINVS(SWVAL)

DESCRIPTION

DoInvisSwitch creates an invisibility switch primitive attribute object.  The parameter switchvalue determines whether subsequent primitive objects will be rendered.  The parameter takes one of the following values:

DcOff <DCOFF>
Render subsequent primitive objects normally.

DcOn <DCON>
Do not render subsequent primitive objects.

DoInvisSwitch provides direct control of the invisibility primitive attribute at the lowest level.  Higher level control is provided through name sets and filters. 

DEFAULTS

The default value for DoInvisSwitch is DcOff <DCOFF>.
