#!N Function #!N #!N Returns a specified component of a specified 
Field. #!N #!N Syntax #!N  #!F-adobe-times-bold-r-normal--18*   #include <dx/dx.h> Object DXGetComponentValue(Field f, 
char *name) #!EF #!N #!N Functional Details #!N #!N Typically, Fields 
have a "positions" component defining a set of points in space, 
a "connections" component defining the connectivity of the positions, and a 
"data" component containing the individual data values associated with the individual 
positions or connections. A Field can be manipulated by accessing these 
components. The following are just two examples: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   
#!N #!N #!I30 #!N o You can transform a Field by 
calling  #!F-adobe-times-bold-r-normal--18*   DXGetComponentValue(field, "positions") #!EF to return the "positions" component, and 
then transforming the points it contains. #!N #!I30 #!N o You 
can convert a Field containing vector data to one containing the 
magnitude of the vector data by calling  #!F-adobe-times-bold-r-normal--18*   DXGetComponentValue(field, "data") #!EF 
to return the "data" component, and then creating a new "data" 
component containing the magnitude data to replace it in the Field. 
#!N #!I0 #!N #!EF #!N #!N #!N Return Value Returns the 
 #!F-adobe-times-bold-r-normal--18*   name #!EF component of Field  #!F-adobe-times-bold-r-normal--18*   f #!EF or returns 
 #!F-adobe-times-bold-r-normal--18*   NULL #!EF and Sets an error code if  #!F-adobe-times-bold-r-normal--18*   f 
#!EF is not a Field. It does not set an error 
code if the component does not exist. #!N #!N See Also
