[chimerax-users] VR movie

[Elaine Meng]

Hi Matthias,
Tom wrote a nice summary of his process for making mixed-reality videos here:

<https://www.cgl.ucsf.edu/chimerax/data/mixed-reality-nov2019/mrhowto.html>

That may address the first and third questions.  

As for the middle question, there is a mouse mode (or VR hand-controller button mode) for bond rotation.  However, my guess is that instead he previously made a morph trajectory between the two conformations and then was using the mouse mode "play coordinates" (flipping through different sets of coordinates in a trajectory model)... Tom would have to confirm whether my guess is correct.   One would generally use the bond rotation mode when zoomed in on atoms/bonds shown as sticks, so that is easy to start the drag on a specific bond.

Mouse modes and their toolbar icons:

I hope this helps,
Elaine

But your way opens up interactive VR to a larger audience (even if they don’t get to enjoy the stereoscopic 3D). And it’s cool.
