NAME

DoDiffuseSwitch − Create a primitive attribute object for enabling or disabling use of the diffuse component of a surface’s response to light

SYNOPSIS

C:

DtObject DoDiffuseSwitch(switchvalue)
DtSwitch switchvalue;

FORTRAN:

INTEGER∗4 DODIFS(SWVAL)
INTEGER∗4 SWVAL

DESCRIPTION

DoDiffuseSwitch creates a diffuse switch primitive attribute.  The switchvalue parameter is used to specify whether or not the surfaces of subsequent primitive objects have a diffuse component in their responses to light from incident light sources in the environment. 

The diffuse switch determines whether diffuse attributes will be used.  If the switchvalue is DcOff <DCOFF>, the primitive object will render itself without diffuse shading.  If the switchvalue is DcOn <DCON>, the primitive object will render itself using the diffuse attributes whenever possible. 

The diffuse switch is one of three aspects of the diffuse component of a surface.  The other two components are the DoDiffuseColor <DODIFC> and the DoDiffuseIntens <DODIFI>. 

DEFAULTS

The default for DoDiffuseSwitch is DcOn <DCON>.
