Visualization

In particular 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

Need to:

• write a function that takes a pyclaw.Solution and gives a list of dicts as described here: http://yt-project.org/docs/3.0/examining/loading_data.html#generic-amr-data
