[yt-users] Real-time histogram presentation based on interactive volume rendered camera properties

[E.M. Dragowsky]

Hi, Matt -- Thanks for offering this assessment of the current state,
including the notion that my interest aligns with future plans.

To aid in my report back to my sponsors, perhaps I can extend this
conversation to determine if there's anything I can contribute to this
development effort? I've described myself as a "researcher who can code",
definitely not to be confused with a practiced developer, and yet...these
topics of volume rendering and coordinated views have become really
interesting to me.

Please let me know,
~ Em

Hi Em,

Thanks for writing.  Right now, this isn't possible; I had delayed on
writing back because I was experimenting with ways of augmenting the
existing OpenGL VR to do this, but I ended up not coming up with anything
in time.  I absolutely think this is where we would like to go with our
interactive VR, but I don't have a timetable for it right now.
