[osg-users] multitouch-capable camera manipulators for terrain?

[Christian Buchner]

Hi,

with the recent addition of Multitouch support for OSG 3.1 on Windows
(thank you whoever committed this), I would like to ask what kind of
support for Multitouch the current camera manipulators have.

I think what could be very useful is an osgGA::TerrainManipulator
where you can grab two points on the terrain with your fingers and
then these points remain attached to your fingers, enabling pinch and
zoom and rotate. With just a single finger we could to a translation.
This would be equivalent to the multitouch support in terrain based
games like R.U.S.E., I think.

Anyway, I will soon test whatever is there with my cheap MEDION
monitor which has a two-point optical recognition built in.

Thanks, that was me.

At least there is a MultiTouchTrackballManipulator (see 
examples/osgmultitouch). I do not have other manipulators.

Regarding the example: The gesture to reset the view is tapping with three 
fingers.  Your Medion devices may have a problem with this.
