[chimerax-users] How to zoom into a spot that is not located in the center gradually and straightly?

[Steve Chou]

Thanks Elaine! This is exactly what I want.
=============
# save current view settings
view save my_view_name

# move to another position, zoom in or out, and color some residues etc

# get back to the original view in 20 frames along a STRAIGHT line
view my_view_name 20
=============

In the 20 frames of transition time, I can not do anything now. Is it
possible to do something during the transition, like changing the surface
transparency? Can we save the view matrix, devide the transition into many
steps, and  do something else ( not motion-related, but coloring-related,
etc) at each step?
Steve
