Hi Mitch, There is an implementation for WM_TOUCH in GraphicsWindowWin32, haven’t tested it personally.
It should be easy to add support for TUIO-touch-events to the existing OscDevice, as TUIO is transported via OSC-messages. There’s also a recipe for intercepting TUIO-events via https://github.com/xarray/osgRecipes/wiki, haven’t worked with it. The multitouch-trackball-manipulator is not specific to the Apple trackpad, as it works with the TouchData of an osg-event and should be device-independent (I’ve tested it it on IOS and OS X). But as Christian already noted, the mt-manipulator is more a proof of concept than a stable working one. It’s hard to extend the existing manipulators, as they are all modeled with a single pointer device in mind. As you can see multitouch is still in its early stages :-) so any help is very appreciated! cheers, Stephan Am 11.09.2013 um 02:29 schrieb Doran, Mitchell (Student) <[email protected]>: > UNCLASSIFIED > > Thanks for the reply, This example seems specific to the Apple Trackpad. > > It may prove useful yet; though there appears to be no bindings to get either > TUIO (touch protocol over UDP) data or WM_TOUCH (Windows) or ABS_MT (Ubuntu) > touch events into the osg environment. > > Its looking like I may have to write my own bindings to get TUIO events > recognized. > > I think I remember seeing somewhere that Stephan had worked on something > similiar. > > Anybody else with any ideas how to get say TUIO events into osg land, what > would I need to implement? > > Mitch. > > From: [email protected] > [mailto:[email protected]] On Behalf Of Christian > Buchner > Sent: Tuesday, 10 September 2013 7:45 PM > To: OpenSceneGraph Users > Subject: Re: [osg-users] OSG Multi-Touch input.
