D3 Filter in ParaView

The D3 filter uses the VTK filter vtkDistributedDataFilter. The D3 filter provides load balancing and data redistribution for any VTK data set. Additionally, the D3 filter automatically computes ghost cells.

  1. First the user selects from the Selection Window the data they wish to operate on. It will be highlighted when this occurs.
  2. The user can then select Filter->Alphabetical->D3 from the main menu.
  3. The user has three options under the Boundary Mode menu. The user can:
    1. Assign cells uniquely across the processes. This works well for isosurfaces.
    2. Duplicate cells across the processes.
    3. Divide cells across the processes. This works well for volume rendering.
  4. The user can force the communication routines to minimize the memory usage, although this is slower.
  5. The Apply button must be pressed before the outline will be generated.

Unlike All to N and Balance, the D3 filter can work on any input data type and preserves spatial regions on processors.
