<div><br></div><div>I'm trying to render a non-cubical volume (observational data: see an early attempt at <a href="https://vimeo.com/67421373" target="_blank">https://vimeo.com/67421373</a>). If I supply a scalar "resolution" to Camera.__init__, the output is a square, even though the input data is ~2x wider than it is tall. If I supply a tuple of values, I can manually stretch the image but, as you can tell from the movie, I want to spin around the volume. I don't think that messing with resolution will help me in this case, since the projected aspect ratio of the plot changes at each rotation step.</div>
<div><br></div><div>I did find an old thread similar to this (<a href="http://lists.spacepope.org/pipermail/yt-users-spacepope.org/2012-July/002793.html" target="_blank">http://lists.spacepope.org/pipermail/yt-users-spacepope.org/2012-July/002793.html</a>), but the recipe there seem specific to axis-aligned slices, and not generic rotations. </div>
<div><br></div><div>Is there a natural way to force yt to render pixels with the "right" aspect ratio?</div><div><br></div><div><br></div><div>Thanks,</div><div>Chris</div></div><span><font color="#888888">
