[yt-users] Camera/Off axis Options

Dear Suoqing Ji: I was able to implement the off axis in my script (drive link below, file is yt_magnetic_fields.py). But there seems to be a problem. For any off axis value like (1,1,0) I get an error which is given below. I am trying to get a z-x plane and view it at an angle of 15,45,60 degrees respectively. It works for along the axis normal vector like (1,0,0) and so on but for off axis value it gives me the error. Could you let me know if there is any error in the script or ways to overcome it? Thanks in advance https://drive.google.com/open?id=0B4g8shg4DL7oak5PLWVVdG5UMHc Error: Traceback (most recent call last): File "yt_magnetic_fields.py", line 39, in <module> slc.save() File "/state/partition1/anaconda/lib/python2.7/site-packages/yt/visualization/plot_container.py", line 77, in newfunc args[0]._setup_plots() File "/state/partition1/anaconda/lib/python2.7/site-packages/yt/visualization/plot_window.py", line 980, in _setup_plots self.run_callbacks() File "/state/partition1/anaconda/lib/python2.7/site-packages/yt/visualization/plot_window.py", line 1033, in run_callbacks sys.exc_info()[2]) File "/state/partition1/anaconda/lib/python2.7/site-packages/yt/visualization/plot_window.py", line 1029, in run_callbacks callback(cbw) File "/state/partition1/anaconda/lib/python2.7/site-packages/yt/visualization/plot_modifications.py", line 316, in __call__ return qcb(plot) File "/state/partition1/anaconda/lib/python2.7/site-packages/yt/visualization/plot_modifications.py", line 837, in __call__ plot.data[self.field_x], File "/state/partition1/anaconda/lib/python2.7/site-packages/yt/data_objects/data_containers.py", line 246, in __getitem__ f = self._determine_fields([key])[0] File "/state/partition1/anaconda/lib/python2.7/site-packages/yt/data_objects/data_containers.py", line 518, in _determine_fields finfo = self.ds._get_field_info("unknown", fname) File "/state/partition1/anaconda/lib/python2.7/site-packages/yt/data_objects/static_output.py", line 543, in _get_field_info raise YTFieldNotFound((ftype, fname), self) yt.utilities.exceptions.YTPlotCallbackError: annotate_magnetic_field callback failed with the following error: Could not find field '('all', 'cutting_plane_bx')' in UniformGridData On Thu, Apr 21, 2016 at 3:46 PM, wrote:

Hi Sushi,

What you need to do this to make use of off-axis slice plot instead of camera; for example, in your code:

L = [1, 0, 0] # View along x axis north_vector = [0, 0, 1] slc = yt.SlicePlot(pf, L, ?magnetic_field_x", width=(100,'km?), north_vector=north_vector) slc.annotate_magnetic_field(factor=40, normalize=True)

which gives you the view along x axis. And if you want to rotate the viewing angle by, say 45 degree, you could change the normal vector L to be L = [1, 1, 0], and redo the plotting.

Also, when you load the data, you probably need to change the name ?field_x? to be ?magnetic_field_x? and so on, so the annotate_magnetic_field function will recognize these names.

Dear Suoqing Ji:

The fields Bx,By and Bz are already calculated taking into account the rotation. So I am not sure if I need to calculate it again.

What I would like is only change the camera view to a desired angle after I do a slice plot and that is where I am having trouble with?

Thanks in advance.

Right, I bet it will work if you do `annotate_velocity()` though.

You should take a look at the definition of the VelocityCallback to see how it handles off-axis slices.

The quiver/streamline option you?ve used works for 2d plotting but not for volume rendering, so I might suggest to use off-axis slice plot: http://yt-project.org/doc/visualizing/plots.html#off-axis-slices < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices> < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices>>

Unfortunately, quiver/streamline does not work (and/or does not work correctly) for off axis slice plot now, but your goal is still achievable via the following steps:

Are you sure about that? There's a `CuttingQuiverCallback` for off-axis slices. If you do `annotate_magnetic_fields`, it will automatically choose the `CuttingQuiverCallback` for off-axis slices.

1. Use fixed resolution buffer to get the off-axis sliced field values including Bx, By and Bz (see this as an example, and replace SlicePlot with OffAxisSlicePlot: http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... < http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedresolutionbuffer#multi-plot-slice-and-projections> < http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... < http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedresolutionbuffer#multi-plot-slice-and-projections>>), then you get a 2D array for each field;

2. Compute the magnetic field vectors projected onto the rotated viewing plane (perpendicular to your normal vector), based on field values of Bx, By and Bz; now you have two 2D arrays for each components of B field vectors after rotation;

3. Use quiver function in matplotlib and plot the B field vectors after rotation, see: http://matplotlib.org/examples/pylab_examples/quiver_demo.html < http://matplotlib.org/examples/pylab_examples/quiver_demo.html> < http://matplotlib.org/examples/pylab_examples/quiver_demo.html < http://matplotlib.org/examples/pylab_examples/quiver_demo.html>>

Hope this helps! Perhaps there?s an easier way that I do not know...

Hi Sushi,

I think the off-axis slice/projection plot will meet your requirement best, where the camera orientation is determined by the normal vector:

http://yt-project.org/doc/visualizing/plots.html#off-axis-slices < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices> < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices>> < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices> < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices>>>

http://yt-project.org/doc/visualizing/plots.html#off-axis-projection-plots < http://yt-project.org/doc/visualizing/plots.html#off-axis-projection-plots> < http://yt-project.org/doc/visualizing/plots.html#off-axis-projection-plots < http://yt-project.org/doc/visualizing/plots.html#off-axis-projection-plots>> < http://yt-project.org/doc/visualizing/plots.html#off-axis-projection-plots < http://yt-project.org/doc/visualizing/plots.html#off-axis-projection-plots> < http://yt-project.org/doc/visualizing/plots.html#off-axis-projection-plots < http://yt-project.org/doc/visualizing/plots.html#off-axis-projection-plots

...

And of course, if you?re interested in the features provided by

volume rendering, it?s also worth a try. This cookbook gives an example of moving a camera; specifically you might want to use the camera.rotation:
