ive been working on this for a little while. we build our own MT devices
in house
for the most part but have used overlays from NextWindow. we just got a
46" one
for about $600ish. im not sure what their smaller sizes run.
as far as MT interaction, ive modified the TrackballManipulator to act on
gesture
events which are shipped over a socket. this works great for single sets
of
geometry. we have a large wall and several large tables, which afford
multiple users
so ive pushed the gesture interaction down into a MatrixManipulator
derivative so
individual heads up display type rectangles and other geometry can all be
active. this
will give you the ability to do the canonical media sorting application,
etc.
you can check out our very out of date blog at
http://vis.renci.org/multitouch which will
have some shots of the vpb globe and whatnot.

Subject: [osg-users] Multi-touch in the OSGViewer and camera manipulators
Hi,
My boss was running my 3D engineering app on a 32 inch touch screen
(no multi-touch yet, I suppose) and he liked how he was able to rotate
the camera with a fingertip.
That gave me an idea - are there any affordable Multi-touch LCD
screens (standalone) and how difficult would it be to add Multitouch
capabilities to OSG? In particular I was wondering what it would take
to support Multi-Touch capabilities in the various Camera manipulators
- and how to get the "special" input events from various operating
systems (Mac, Windows, Linux).
In particular zooming with two fingers would be extremely cool ("the
pinch" gesture) , and grabbing an object with two fingers, rotating it
(or the camera around it) in the 3D view according to how the two
fingers move.
Christian
