Plot of array of shape (N, N, N) in form of sphere

Community matplotlib-users

Dear All,

I have an array of shape (N,N,N) of intensity values. How can I plot those
intensity values in form of sphere.
Can I show a cut of quadrant of that sphere, so that I can visualize
intensity not only on the surface but also inside the sphere.

Thanks

This sounds like something you'd want to use yt or mayavi for. While MPL
has basic 3D capabilities (e.g., scatter, line, and surface plots), taking
cuts of volumes is definitely out of our scope unless you've pre-computed
everything.

Another fantastic tool is glumpy: https://glumpy.github.io/ (but I am not
familiar enough with the API to know how to do volumetric displays). vispy
is another possibility, but I am unsure of its current status (it went
silent about a year ago).

Here is a notebook that illustrates how to work with volumetric data in
Plotly:
http://nbviewer.jupyter.org/github/empet/Plotly-plots/blob/master/Plotly-Slice-in-volumetric-data.ipynb
<http://nbviewer.jupyter.org/github/empet/Plotly-plots/blob/master/Plotly-Slice-in-volumetric-data.ipynb>
Another possibility is to define a slice in a volume as a triangulated
isosurface, via skimage.measure.marching_cubes.
