Im using osgViewer with an exisiting rendering engine as an embedded window.
But i dont want to use the GUIEvent handler, as Im handling the events myself.
I have followed the osgpick example, normally the x,y mouse pos is retrieved
from the osgGA::GUIEventAdapter with the values[0,1]. I am passing the actual
mouse coords [0,windowsize] to a method with the following code, scaling the
values to [0,1] based on window size, but i Never get any hits..! Do you see
what im doing wrong here?
CODE:
std::string Pick(int mouse_x, int mouse_y)
{
osgUtil::LineSegmentIntersector::Intersections intersections;
int wx,wy,ww,wh;
_window->getWindowRectangle(wx,wy,ww,wh);
float x = (float) mouse_x / (float)ww; //ea.getX();
float y = fabs((float) mouse_y / (float)wh); //ea.getY();
if (_viewer->computeIntersections(x,y,intersections))
{
for(osgUtil::LineSegmentIntersector::Intersections::iterator hitr =
intersections.begin(); hitr != intersections.end(); ++hitr)
{
if (!hitr->nodePath.empty() &&
!(hitr->nodePath.back()->getName().empty()))
{
return hitr->nodePath.back()->getName();
}
else if (hitr->drawable.valid())
{
return "No name";
}
}
}
return "";
}
using osg 2.3.7 on vista-
Thanks!
