It is possible to slice and clip a volume with a surface by using a Python Programmable Filter. This relies on the vtkImplicitPolyDataDistance , so the result is an approximation, not an actual boolean operation. Steps for clip: Open a volume, apply Open a surface, apply In the pipeline browser, …

How difficult would this be to parallelize for large volume data?

If your volume is partitioned across ranks, you should be able to use these scripts as written. You just need to make sure copy of the entire surface is duplicated on each rank, which can be done with the Append Reduce filter with the Reduction Mode set to “Reduce all data to all processors”
