Optimization of the display function

ParaView Support

Well, we do not have an explicitly “slow” method and a “quick” one. So one need to investigate what exactly is long in your case.

In fact, different things occurs behind the Show:

  1. update the whole upstream pipeline (if needed). In a script case, the first Show will trigger the reader for instance.
  2. create the Representation object, i.e. prepare data for rendering. With GeometryRepresentation, it extracts the external surface of the mesh, create a default colormap, etc…

The 1. can also be done with UpdatePipeline, so you can see which part is long.

For more timing details, you look at the execution logger. See --log and --verbosity option of paraview / pvpython. In the interface, go to Tools / Log viewer.

For instance

./bin/pvpython --log=output.log,TRACE
