Visualization

Updates:

• We have successfully plotted a slice of AMRClaw data with yt!
• Here is the script: https://gist.github.com/ketch/30d8bdf41422dc20bb95

To do:

• Add switch for yt plot backend in visclaw
• Add plotitem3 function in visclaw.frametools
• Add some 3d plots to the gallery

Monday afternoon discussion:

3D options for plotting: which option should we target?

• yt - Originally analysis toolkit for astronomy, now more general
  • Does AMR natively
  • Need backend, basic things with matplotlib's mplot3d
  • Does cut-planes, iso-surfaces, streamlines...
  • Includes analysis tools
  • Reads a bunch of AMR data formats and some parallel capabilities but limited for both
  • New version (3.0.1) seems to be the thing to target
• VisIt
  • Handles AMR "out of the box"
• Paraview
  • XMDF - Meta-data file for VTK files, used in Paraview
  • Poor python interface

General conclusion - Implement yt as at least a first step. Going to test with simple advection in AMR.

Example yt script to do a volume rendering of a BoxLib dataset: magvort.py
