[Paraview-developers] Catalyst: Saving memory with no-copy adapters

Hi folks,

ParaView is being used for live analysis and visualization of running
simulations though the Catalyst coprocessing library, and until now it was
necessary to copy the simulation dataset into a VTK container so that it
could be used in a pipeline. This essentially doubled the memory
requirements for the dataset when coprocessing is used.

New work in VTK allows external memory to be used with a VTK dataset
interface. The new classes and methods that make this possible are
described on the Kitware blog:

and detailed on the VTK wiki:

Happy computing!
Dave
