I would like to produce both a sphere and a polar plot whose surface color is defined at each XYZ axis as follows:
Top-bottom (Z) = blue
Left-right (Y) = red
Anterior-posterior (X) = green
The color in the boundaries/interfaces should be an interpolation of them.
Such as here:
and here (for the polar plot):
I have been googling for a while but did not find much help to do it.
PS: Similar questions seem to have been asked previously with a few variants, but the answers given seem not reproduce the figures pointed above.
