Here is the description of the --view option from section 6.5.5 of the  
MNE manual:

--view <name>

Select the name of the view for mov, rgb, and tif graphics output  
files. The default viewnames, defined in $MNE_ROOT/share/mne/ 
mne_analyze/eyes, are lat (lateral), med (medial), ven(ventral), and  
occ (occipital). You can override these defaults by creating the  
directory .mne under your home directory and copying the eyes file  
there. Each line of the eyes file contais the name of the view, the  
viewpoint for the left hemisphere, the viewpoint for the right  
hemisphere, left hemisphere up vector, and right hemisphere up vector.  
The entities are separated by semicolons. Lines beginning with the  
pound sign (#) are considered to be comments.

The viewpoints are controlled by the "eyes" file. As you can see from  
the above, you can create a personalized copy in $HOME/.mne directory.  
The default options in addition to lat are: med, ven, and occ.

I hope this helps

- Matti
