MARS

Deliverables

ParaView/Titan Chart Merger (Pat/Utkarsh)

Starting work on options dialog. After that, start trying it out.

Dave Thompson has list of features he would like to see for the dialog.

Simplified Scripting (Berk/Utkarsh)

Looking at replacing array calculator with python-based calculator. Made some good progress. Does everything current calculator but also a lot more. Berk has 10-line calculator to do gradients.

There is a deployment issue in that right now this code depends on NumPy and MPI wrappings. To get around the MPI wrappings, we should work on getting vtkMultiProcessController properly wrapped.

To handle the finding/loading of these python modules, we should modify the CMake files to look for these things and warn if they are not there (identifying what features will be missing). The user can then install them and run CMake again to add them in.

Upcoming are some changes to allow you to references input properties without dereferencing output ports. There will also be improvements with proxy properties that have list domains.

Temporal Cleanup (Berk)

  • Show temporal bounds of all datasets in statistics view (or elsewhere)
  • Show continuous data set temporal bounds in info page
  • Plot/Probe over time, results should very in Sequence, Snap, and Real Time modes

Not started yet. John Biddiscombe has been looking at it.

Plots Along Curves (Berk)

Not started

VisIt AVT Integration (Burlen)

Getting material stuff working. Parallel is now working for databases that provide multiple domains. If fewer domains than processors, some will be empty.

Working on AMR.

Statistics (Phillipe)

Some backpedaling here. The statistics filters may not be ready because (1) there needs to be a mechanism to take a data object rather than a table (auto conversion) and (2) there needs to be some further changes to handle multicomponent arrays correctly.

Particle Support (Zhanping/John Biddiscombe)

  • Provide a particle representation that renders points more intelligently
    • Spheres with size vs. squares of pixel width
    • Optional sizing based on a scalar
    • Appropriate alpha blending (at least when particles are small)
    • Splatting?
  • Filters for meshless data? (Need to get customer requirements.)
    • Sampling point cloud?
    • Surface extraction?

Not started yet.
