Re: [Jmol-users] select molecules based on xy coordinates

[Benn S. <ben...@gm...>]

Basically, I have xyz coordinates of the user's hand position.  The xy
origin is in the center of the Kinect's camera view.  The z origin is at
the camera with z representing the distance from the camera.  I want to
allow the user to "point" at an atom (or bond, but that will come later)
and select it along with all connected atoms as if they were using the
mouse.  findAtomsInRectangle could indeed be useful - can I call it from a
script/socket?

Thanks for your help.


Regards,
Benn
