Thanks for the input, Tom. I've been playing with ChimeraX now and find
that there are features still missing (understandably) which will limit
the presentation, such as not having zone selection with extend, hbonds,
and something equivalent to focus.
While I may be able to come up with their rough equivalents to achieve
the desired results, I'm not sure my students would be up to the task.
The idea is to make it a bit of a challenge but more importantly to be
fun seeing things come together relatively quickly.
Back to Chimera itself--can a side-by-side movie be generated which
would work in a VR setup? If so, what sorts of changes might we look
for in the settings for the camera (eye separation, screen distance,
This moves away from the immersion experience but still could easily
bring a student's presentation outside to the masses to view...
