NAME

DoDiffuseColor − Create a diffuse color primitive attribute object

SYNOPSIS

C:

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

FORTRAN:

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

DESCRIPTION

DoDiffuseColor creates a diffuse color primitive attribute using the color model specified by colormodel.  The color parameter specifies the diffuse response of a surface to light. 

Diffuse reflectance is the response of a surface to incident (i.e., non-ambient) light where the emitted light is scattered equally in all directions.  The diffuse color of a surface is often thought of as the base color. As such, the diffuse color is also used for determining the color of the ambient component of a surface. 

The diffuse color is one of three aspects of the diffuse component of a surface.  The other two components are DoDiffuseIntens <DODIFI> and DoDiffuseSwitch <DODIFS>. 

DEFAULTS

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