I've spent some time looking at the polar coordinate handling in yt-3.0 this morning and I believe I have come up with the current status.</div>
<div><br></div><div>As it stands, the actual creation of a nice plot like yt normally does -- through the PlotWindow object -- is not yet possible. There are a few more steps that need to happen before everything can be nicely integrated like that. However, I have refreshed my memory on the coordinate handling system, and I have been able to make some nice images relatively easily.</div>
<div><br></div><div>The code had to have a few changes to support this; I've put these changes into a pull request here:</div><div><br></div><div><a href="https://bitbucket.org/yt_analysis/yt-3.0/pull-request/82/fix-flash-polar-cylindrical-pixelization/diff" target="_blank">https://bitbucket.org/yt_analysis/yt-3.0/pull-request/82/fix-flash-polar-cylindrical-pixelization/diff</a><br>
</div><div><br></div><div>You can get them by doing:</div><div><br></div><div>cd $YT_DEST/src/yt-hg/</div><div><br></div><div>(or wherever your yt-3.0 installation is) and doing:</div><div><br></div><div>hg pull -r 12101b782ac8 <a href="https://bitbucket.org/MatthewTurk/yt-3.0" target="_blank">https://bitbucket.org/MatthewTurk/yt-3.0</a></div>
<div>hg up -r 12101b782ac8</div><div>python2.7 setup.py build_ext -i -f</div><div><br></div><div>(the -f will force every extension to rebuild; if you get funny errors with selector objects being the wrong size, you may need to do: "find . -name '*.pyx' | xargs touch" and then another build_ext run.)</div>
<div><br></div><div>This script then created the correct output for me: <a href="http://paste.yt-project.org/show/3788/" target="_blank">http://paste.yt-project.org/show/3788/</a></div><div><br></div><div>I've tested it on a few NIF items. The changes I made were specifically in how the data is expected to be ordered; I'd incorrectly had cylindrical as rtz and polar as rzt in FLASH. I've switched these in the PR.</div>
<div><br></div><div>Roman, Suoqing and Anthony, I've listed you as reviewers on the PR because I know you have all looked at polar and/or cylindrical data in the past. If you could give some feedback, and especially let me know if I have done something wrong.</div>
<div><br></div><div>In the future, I would like to have things working such that we can do SlicePlot( ... ) like normal. That will require a somewhat detailed discussion with PlotWindow experts about how to set up bounds for a window, but I think it should be doable in the not-too-distant future.</div>
<div><br></div><div>Let me know if that works for you, and if you need any more help!</div><div><br></div><div>Best,</div><div><br></div><div>Matt</div></div><div class="gmail_extra"><br><br><div class="gmail_quote"><div class="im">
