NAME

DoTextureMapBumpSwitch − Create a primitive attribute object for enabling or disabling bump mapping

SYNOPSIS

C:

DtObject DoTextureMapBumpSwitch(switchvalue)
DtSwitch switchvalue;

FORTRAN:

INTEGER∗4 DOTMBS(SWVAL)
INTEGER∗4 SWVAL

DESCRIPTION

DoTextureMapBumpSwitch creates a primitive attribute object that enables or disables bump mapping, that is, perturbing shading normals by using a texture map.  The switchvalue parameter is used to specify whether or not the shading normal of subsequent primitive objects can be modified by bump mapping. 

DcOff <DCOFF>
The primitive object will ignore any bump maps that have been defined with DoTextureMapBump <DOTMDC>. 

DcOn <DCON>
The primitive object will be bump mapped as specified by the DoTextureMapBump attribute, whenever possible. 

DEFAULTS

The default for DoTextureMapBumpSwitch is DcOff <DCOFF>.
