Thank @Remi-Gau !
I wonder if we should add 'texture'? It's not used a lot in the docs but more so as a variable name when it equals an array projected on the surface

yes definitely

I had listed also:

• coordinates
• geometry

But they feel too generic, no?

[Remi-Gau]

if we should add 'texture'?

Only mentioned once: nilearn/examples/01_plotting/plot_3d_map_to_surface_projection.py:53

So maybe not?

[bthirion]

No strong opinion on "textures". We could also use it more frequently...

[Remi-Gau]

Would suggest to merge this as is and add texture later

[bthirion]

Good with me.
