<div class="Section1">
<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal">I am trying to figure out how to plot cell data so that cell faces that are on boundaries between different scalar values are visible. For example, I have structured grid data representing a 3x3x3 block of cells composed of two materials
with one material block of 3x3 cells sandwiched between the other . If I turn off the center layer material (by making it transparent or using vtkStructuredGrid::SetCellVisibilityArray()) I would like to see the solid faces of the other material. Two images
are attached to illustrate – one from a simple graphics program showing cell surfaces on all boundaries and the other my attempt with vtk showing missing cell faces on the boundaries.<o:p></o:p></p>
<p class="MsoNormal">Can anyone tell me if there is a filter to plot boundaries between scalar values in a single vtkCellData? I tried toggling backface and frontface culling, but this is not the issue. The only other way I could think of to accomplish this
is to set up separate structured grids for each material, but this seems inefficient. <o:p></o:p></p>
<p class="MsoNormal">Thanks for your help,<o:p></o:p></p>
