Rendering Properties #!N #!N #!N You can change the rendering properties
of an object by using the Options module. The following table
lists the shading attributes that can be set by the Options
module for interpretation by the Display tool. (See the section on
surface shading in IBM Visualization Data Explorer Programmer's Reference for more
information.) #!T,1,121,241,361,641 #!F-adobe-times-bold-r-normal--18* #!N TAB Attribute TAB Type TAB Default TAB

TAB coefficient of diffuse reflection k[d] #!N TAB "specular" TAB scalar
TAB .5 TAB coefficient of specular reflection k[s] #!N TAB "shininess"
TAB integer TAB 10 TAB exponent of specular reflection sp As
a rule of thumb, except for purposes of special effects, #!F-adobe-times-medium-i-normal--18*
k[a] #!EF should be #!F-adobe-times-medium-i-normal--18* 1 #!EF and #!F-adobe-times-medium-i-normal--18* k[d] +
k[s] #!EF should be about 1. The larger #!F-adobe-times-medium-i-normal--18* k[s] #!EF
, the brighter the highlight, and the larger #!F-adobe-times-medium-i-normal--18* e #!EF
, the sharper the highlight. The Shade module provides a shortcut
for setting rendering properties. #!N #!N The attributes listed above apply
to both the front and back of an object. In addition,
for each attribute " #!F-adobe-times-medium-i-normal--18* x #!EF " there is also
a "front #!F-adobe-times-medium-i-normal--18* x #!EF " and a "back #!F-adobe-times-medium-i-normal--18* x
#!EF " attribute that applies only to the front and back
of the surface, respectively. So, for example, to disable specular reflections
from the back surfaces of an object, use the Options module
to set the "back specular" attribute of the object to 0.
#!N #!N The determination of which faces are "front" and which
are "back" depends on the way in which the "connections" component
of the faces is defined. "Front colors" applies to clockwise faces,
and "back colors" applies to counterclockwise faces. #!N #!N #!N #!F-adobe-times-medium-i-normal--18*
