Hi Joan,
I'm using osgManipulator with vrjuggler and it works quite well.
You juste have to create a dummy osgGA::GUIActionAdapter en create a
osgGA::GUIEventAdapter that maps VRJuggler events.
I recently introduce the possibility in PointerInfo to use a VR device instead
of a mouse.
Beware that for translations, current manipulators should do fine, but using
them for rotations is a bit awkward, you'll have to develop you own
manipulators.
Just define
**************************************************************************
class DummyActionAdapter : public osgGA::GUIActionAdapter{
void requestRedraw(void){};
void requestContinuousUpdate(bool){};
void requestWarpPointer(float,float) {};
};
************************************************************************
And in OsgNav::preFrame() :
**************************************************************************************
const osg::ref_ptr<osgGA::GUIEventAdapter> ea = new osgGA::GUIEventAdapter();
DummyActionAdapter aa;
switch (mButton2->getData())
{
case gadget::Digital::TOGGLE_ON:
{
ea->setEventType(osgGA::GUIEventAdapter::PUSH);
osgUtil::LineSegmentIntersector::Intersections intersections;
_pointer.reset();
osgUtil::LineSegmentIntersector * picker = new
osgUtil::LineSegmentIntersector(wandTrans,wandDir);
osgUtil::IntersectionVisitor iv(picker);
mRootNode->accept(iv);
etc. (same thing as with osgViewer)

Objet : [osg-users] Using the osgManipulator Draggers withosgUtil::SceneView
(fwd)
I would like to use one of the osgManipulator::Draggers. However, I am using
osgUtil::SceneView and dont have any osgViewer::Viewers. Also my application
is using vrJuggler and vrJuggler is what is getting the keyboard mouse events
and I am getting them from vrJuggler. From what I determined from the
osgmanipulator example and by looking around at your source code is that I have
to call handle on the Dragger every frame and pass it an
osgManipulator::PointerInfo, osgGA::GUIEventAdapter, and
osgGA::GUIActionAdapter. However, since I am not using a Viewer I don't have
these. I am thinking that I have to create a GUIEventAdapter and set the key
and mouse information that vrJuggler is passing me and use that one with the
Dragger. Same witht the PointerInfo. Am I on the right track or is there some
other way that I should be going about this?
Thanks
Joan Slottow
