NAME

DoSpecularColor − Create a specular color primitive attribute object

SYNOPSIS

C:

DtObject DoSpecularColor(colormodel, color)
DtColorModel colormodel;
DtReal color[];

Fortran:

INTEGER∗4 DOSPCC(COLMOD, COLOR)
INTEGER∗4 COLMOD
REAL∗8 COLOR(∗)

DESCRIPTION

DoSpecularColor creates a specular color primitive attribute object.  The parameter colormodel specifies the color model used.  The parameter color specifies the specular response of a surface to light from directed light sources in the environment. 

Specular reflection is the response of a surface to directed incident light where the reflected (specular) light is scattered primarily in the mirror direction.  In effect, the specular chromatic response of a surface can be thought of as the color of its shiny highlights. 

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

DEFAULTS

The default DoSpecularColor is (DcRGB, (1.0, 1.0, 1.0)).
