Translucent Highlights 1337
The width of the w hite highlig ht c urve and
the highlights in the preview change. At 0%
anisotropy, both highlight curves are the same
and the highlight is circular, as in Blinn and
Phong shading. At 100% anisotropy, the w h ite
highlight curve and the highlights are extremely
narrow.
To adjust the or ientation of a highlight (specular )
layer:
•ChangethevalueofOrientation.
Highlig hts in the preview show the change in
orientation. The display of the highlight curve
does not change.
Inter face
The First Specular Layer and Second Specular
Layer groups have identical controls, which can
have different settings.
Co lor—Controls the specular color (page 3–1108)
of this highlight. The specular color is the color of
the highlight on a shiny surface.
Leve l—Affects the intensity of this specular
high light. As you increase the value, the highlight
grows brighter. Default: First layer=5, Second
layer=0.

you can also assign specu lar level mapping in the

Glossines s—Affe cts the siz e of this spec ular
highlight. As you increase the value, the highlight
gets smaller and the material appears shinier.
Default=25.

. This button is a shortcut: you can
also assign specular level mapping in the
Maps
rollout (page 2–1315)
.
Anisotropy—Controls the anisotropy, or shape, of
this highlight. At 0, the high lig ht is round. At 100,
the highlight is extremely narrow. One axis of the
Highlight g raph changes to show changes in this
parameter. Default=0.
Orientation—Changes the orientation of this
highlight. The sample slot shows changes in
orientation. This is a value in degrees that can
range from 0 to 9,999. Default=0.
Highlight graph—These two intersecting curves
showtheeffectofadjustingthevaluesofLevel,
Glossiness, and Anisotropy. As you decrease
Glossiness, the curves grow wider; as you increase
Specular Level, the curves grow taller . As you
adjust Anisotropy, the white curve changes to
show how wide or narrow the hi ghlight is.

Like the Blinn shader, the Translucent shader has
circular highlig hts.
