Interactive 3D plot of a Planck map with Matplotlib


May 20, 2024

This is an update of my older tutorial

Unfortunately I was not able to make Mayavi properly plot the data, rerunning the same code would give a map that looked like uniform noise.

This test instead uses matplotlib, unfortunately this is extremely slow, and the output map is really slow to rotate or interact at all. Anyway it is possible to tweak xsize,ysize to change the resolution as a trade-off between resolution and interactivity.
