I apologize for having messed up the thread. I had some problems receiving
email. Your message did not reach me. The only way I found to continue our
"conversation" was answering an old message.

Below is our conversation:

 

Moacyr:

I will try to implement multi-projection in Jmol in a few weeks.

Bob:

Excellent. What I'd like to do is spend some time chatting with you (by
email, perhaps, or Skype). It sounds like this could involve some rather
"deep" code changes, so I want to be sure that we have a clear plan before
starting. Sounds like there are some good standards out there, so this might
actually be very simple. Do you have references to these standards? Looking
forward to working with you.

Moacyr:

My question is due to the following situation:

Imagine a molecule being displayed in an environment with three projectors
(left, front, right). Initially the molecule is viewed in its entirety on
the front. When the observer apply zoom, some atoms do not appear on the
front and begin to appear in the projection right (or left or both), so that
the images create the illusion that the observer is inside the molecule (see
atoms in front and sides). Obviously the lateral projections have different
viewing angles with respect to the central projection.

I already implemented the synchronism between the projections. There is
still need to adjust the appropriate angles for each projections.

Bob:

Sounds like stereo in threesomes. Just three perpendicular views from the
same camera position

Moacyr:

I read http://chemapps.stolaf.edu/jmol/docs/misc/navigation.pdf and
concluded that there is no control of the camera  position. Am I right?

Please tell me which part of code I could make changes to reposition the
camera (observer's position) relative to the molecule. It would be in
TransformManager? Or in TransformManager10? What are the variables involved?

Can we start this over? I lost the sense of the thread. What exactly would
you like to be able to do. Suggest some command options.

Moacyr, 


By the way, the way we would do this, I think, is just the same as we do
stereo -- rerender x times and capture the screen image each time, then put
those together for delivery. Be aware that Java has some memory size
limitations that could put a cap on buffer size. What sort of screen pixel
counts are we talking about here?

Is it possible to run Jmol in a virtual reality environment, such as a CAVE?

It would require that the software could generate 5 different views of the
molecule, one for each wall of the CAVE.

 

Any suggestion?
