[vtkusers] grid cell vis
morandi at zurichmedtech.com

Hi VTK users
I'm trying to visialize cells in a vtkRectilinearGrid that satisfy
certain requirements, e.g cell data value is > 0. Basically I'd like to
see the outer faces of those cells.
I already succeeded in my task by
1. using a vtkExtractRectilinearGrid filter
2. passing it to a vtkThreshold filter
3. using a vtkDataSetMapper.
However, the visualization is quite slow and unresponsive, for large
grids memory consumption is too high. I assume this has to do with the
unstructured grid that is created by the threshold filter.
Does anybody see a more effective approach to visualize a subset of
cells in a rectilinear grid?
Any help is appreciated.
