Details #!N #!N This module is applicable only to surface objects 
(i.e., objects with connections of type "triangle" or "quad"). #!N #!I0 
#!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   input #!EF #!EF #!I50 #!N 
specifies the object whose shading attributes are to be modified. #!N 
#!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   shade #!EF #!EF #!I50 #!N turns shading 
on or off. By default, the module turns shading on. #!N 
#!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   how #!EF #!EF #!I50 #!N specifies whether 
the shading is to be smooth or faceted. If this parameter 
is not set, and: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 
#!N o if the input object is already shaded, the shading 
method is not changed. #!N #!I30 #!N o if the object 
is not shaded, the choice between smooth and faceted shading is 
determined by the dependency of the "data" component, if it has 
a data dependency: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N 
smooth shading is used for position-dependent data. #!N #!I30 #!N faceted 
shading is used for connection-dependent data. #!N #!I0 #!N #!EF #!N 
#!N #!I30 #!N o if no data are present, smooth shading 
is used. #!N #!I0 #!N #!EF #!N #!N #!N An explicit 
specification of "smooth" or "faceted" shading will apply to all objects. 
However, if a "normals" component of the requested type ("dep" "positions" 
or "dep" "connections") is already present, the normals are not recomputed. 
#!I0 #!N #!N #!N #!N The next four parameters specify the 
particular shading attributes of the object. If any of these parameters 
are not explicitly set, the corresponding attributes remain unchanged. #!N #!I0 
#!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   specular #!EF #!EF #!I50 #!N 
specifies the amount of light reflected by the object (as from 
a very smooth, highly reflective surface). The specified value must be 
between 0 and 1. The default is 0.5. #!N #!I0 #!N 
 #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   shininess #!EF #!EF #!I50 #!N specifies how sharp the 
specular highlight is. The specified value must be an integer. Larger 
numbers result in a smaller, sharper, specular highlight. The default is 
10. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   diffuse #!EF #!EF #!I50 #!N 
specifies how much light is diffused by the object (as from 
a rough non-reflective surface). The specified value must be between 0 
and 1. The default is 1 (one). #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*   
 #!F-adobe-times-bold-r-normal--18*   ambient #!EF #!EF #!I50 #!N specifies how much light is 
reflected equally in all directions. The specified value must be between 
0 and 1. #!I0 #!N #!N #!N #!N #!N #!N #!I0 
#!N Notes: #!N #!I30 #!N 1. The Shade module will also 
check whether the orientation of the "connections" component is consistent with 
the directions of the "normals." If they are not consistent, it 
will modify the directions of the normals. #!N #!I30 #!N 2. 
Smooth shading is not supported for faces, loops, and edges data. 
However, faces, loops, and edges can be converted to triangles using 
Refine, and can then be smooth-shaded. #!I0 #!N #!N #!N #!N 
Components #!N #!N May add or modify the "normals" component. All 
other components are unchanged. #!N #!N Example Visual Programs #!CForestGreen #!N
