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%3E 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:
http://yt-project.org/doc/cookbook/complex_plots.html#moving-a-volume-render... < http://yt-project.org/doc/cookbook/complex_plots.html#moving-a-volume-render...
Best wishes,

Hi SK,
I'm going to reference this example:
http://yt-project.org/doc/visualizing/streamlines.html?highlight=streamlines < http://yt-project.org/doc/visualizing/streamlines.html?highlight=streamlines
specifically this snippet:
for stream in streamlines.streamlines: stream = stream[np.all(stream != 0.0, axis=1)] ax.plot3D(stream[:,0], stream[:,1], stream[:,2], alpha=0.1)
Here, the 'stream' object is just a Nx3 numpy array, where N is the
number
of points sampled along the streamline. So each row of the numpy array
is
just the coordinates of the streamline along one direction.
To answer your question, no, there's nothing in yt that will rotate the streamlines into a new coordinate system. Fortunately you should be
able to
do it yourself using e.g. an Euler angle rotation matrix. You will
need to
identify the new coordinate system you would like to transform to, calculate a 3D rotation matrix, then apply it using matrix
multiplication
(e.g. np.dot, which supports broadcasting) to each coordinate along the streamline.
Hope that helps,
Nathan

Pleas correct me if I am wrong but "off axis slices" takes slices of

However, I would like to plot my data in a new coordinate frame

Or I would like to plot my data in a rotated frame (x`,y`,z`), which

Hi Jonah,
I am able to load the data to yt now using load_amr_grids(). I
notice
that it can also set geometry to spherical. This is great. But to
make
life more complicate. Is it possible to let yt know that the grid is logarithmic? Currently, load_amr_grids() just take left and right
edges
of
each block. I guess yt assumes the grid is uniform between left and
right
edges. Is it possible to provide arrays of coordinate values for
each
cell
in each block?
Thanks.

Hi Yanfei,
This is possible -- but it will also slow some things down. You can use the load_hexahedral_mesh function, and there're examples of
this.
This takes away some of the optimizations that regular grids can do, but we're hoping to add them back in shortly. Like the other functions it too takes a geometry argument.

Hi SK,
I'm not sure I totally understand, but if you have an inclination angle you can use this directly in yt in the off axis slices and so on. They typically take a vector, but you should be able to convert one to the other.

Hi Yanfei,
To add to Matt's comment. Here is the documentation for using load_hexahedral_mesh.

Best, Jonah

Hi Yanfei,
This is possible -- but it will also slow some things down. You
can
use the load_hexahedral_mesh function, and there're examples of
this.
This takes away some of the optimizations that regular grids can
do,
but we're hoping to add them back in shortly. Like the other functions it too takes a geometry argument.
