hi
sorry but,
...
I m totally lost,
What I trying to do is is using QT with OSG.
like I said before, I try to get the geode that I ve just clicked (x, y).
like you said, I m now using Intersections. like that I suppose
osgUtil::LineSegmentIntersector::Intersections inter;
if(CGeneral::instance().viewer->computeIntersections((float)event->x(),
(float)event->y(), inter))
{
for(osgUtil::LineSegmentIntersector::Intersections::iterator hitr=
inter.begin();hitr!=inter.end(); ++hitr)
{
but I have an error
Interface.cpp:66: error: 'class SimpleViewerQT' has no member named
'computeIntersections'
SimpleViewerQT are like that declared like that
class SimpleViewerQT : public osgViewer::SimpleViewer, public
GraphicsWindowQT
I looked
http://www.openscenegraph.net/documentation/OpenSceneGraph/examples/osgpick/osgpick.cpp
and on osgCamera
but he use osgProducer (exacly like that I used too)
is it possible do get intersections with osgSimpleViewer??
there certainly something wrong with me but I don't know what
thanks for all

osgViewer::Viewer isn't meant to be used like these, one attaches
GraphicsWindow's to the Camera's that the Viewer maintains. See the
osgcamera example if you want to know how.
