What is the best way to highlight selections with VTK? Creating a separate mesh with just the selected cells a different color is not reliable because VTK doesn't allow polygon offset to be set independently. So sometimes the highlight cells show up and some times they end up obscured. Individually recoloring cells in the mesh seems inefficient and would probably require a full rebuild of the mesh rendering geometry, correct? Paraview I notice highlights cell edges by making the line widths bigger, probably for this very reason. I'd prefer the visual effect to be for cells to change color though. Any ideas?
