#!N Functional Details #!N #!N The ShowBoundary module creates a field 
containing only the exterior faces of the input object. #!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 
is the object whose boundary is to be "shown" by the 
module. #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*    #!F-adobe-times-bold-r-normal--18*   validity #!EF #!EF #!I50 #!N 
determines whether validity of data (as specified by "invalid position" and 
"invalid connections" components) is to be used in constructing the boundary. 
By default, such information is not used, and the information is 
simply passed through to the output boundary. Display, Image, or Render 
will not render any invalid faces. (See  #!Linval,dxall211 h Invalid Positions and Invalid Connections Components  #!EL  in IBM Visualization 
Data Explorer User's Guide for a discussion of invalid data.) #!I0 
#!N #!N #!N #!N #!I0 #!N Notes: #!N #!I30 #!N 1. 
Any colors or data in the input object are passed through 
to  #!F-adobe-times-bold-r-normal--18*   output #!EF . A default color is added if 
a "colors" component is not already present. #!N #!I30 #!N 2. 
The boundaries of a volumetric field are a surface or a 
set of surfaces; the boundary a 2-dimensional field is a line 
or a set of lines. #!I0 #!N #!N #!N #!N Components 
#!N #!N Creates new "positions," "connections," and "normals" components. All other 
components are propagated to the output. If  #!F-adobe-times-bold-r-normal--18*   input #!EF does 
not have a "colors" component, one is added. Adds a "normals" 
component if the input is a volumetric field. #!N #!N Example
