Take a snapshot of a PyVista Scene and project channels onto 2d coords.
Note that this will take the raw values for 3d coordinates of each channel,
without applying any transforms. If brain images are flipped up/dn upon
using imshow
, check your matplotlib backend as this
behavior changes.
Figure3D
The figure on which you’ve plotted electrodes using
mne.viz.plot_alignment()
.
DigMontage
or Info
| dict
The digital montage for the electrodes plotted in the scene. If
Info
, channel positions will be pulled from the loc
field of chs
. dict should have ch:xyz mappings.
Whether to remove the spheres in the scene before taking a snapshot.
The sensors will always be shown in the final figure. If you want an
image of just the brain, use mne.viz.Brain
instead.
