There are some solutions for two-point multitouch, for more tracked points there are some solutions on the horizon, but IMHO not available yet. Most multitouch solutions use back-projection and capturing the field of input with a infrared-camera with the help of infrared-laser, -leds. > and how difficult would it be to add Multitouch > capabilities to OSG?

There's an opensoruce protocol called tuio which sends a stream of events via UDP to a host. So you can change tracking solutions without changing your source. > 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. There's no infrastructure in osg yet, but you can easily adapt some of the matrixmanipulators and add multitouch--support. here you'll find some links: http://delicious.com/sth/Multitouch Hope that helps, Stephan _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
