NAME

DoSpecularSwitch − Create a specular switch primitive attribute object

SYNOPSIS

C:

DtObject DoSpecularSwitch(switchvalue)
DtSwitch switchvalue;

Fortran:

INTEGER∗4 DOSPCS(SWVAL)
INTEGER∗4 SWVAL

DESCRIPTION

DoSpecularSwitch creates a specular primitive attribute object.  The parameter switchvalue specifies whether the surfaces of subsequent primitive objects have a specular component.  Possible values are:

DcOff <DCOFF>
The object will render itself without specular shading regardless of the settings for specular color, specular intensity, and specular factor.

DcOn <DCON>
The object will render itself using the specular attributes whenever possible.

The specular switch is only one of four aspects of the specular component of a surface.  The other components are the specular color, the specular intensity, and the scattering of the specular reflection. 

DEFAULTS

The default for DoSpecularSwitch is DcOff <DCOFF>.
