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 Visual Programs #!CForestGreen #!N #!N #!F-adobe-courier-bold-r-normal--18* #!N InvalidData.net #!N Thunder_cellcentered.net #!N UsingCompute.net #!N SIMPLE/ShowBoundary.net #!EF #!N #!N #!EC #!N #!N See Also #!N #!N #!Lshowbox,dxall944 h ShowBox #!EL , #!Lshowcon,dxall945 h ShowConnections #!EL , #!Lshowpos,dxall946 h ShowPositions #!EL #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lshowbox,dxall944 h ShowBox #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
