Hi osg-users, I am trying to do a very simple application, and when I was required to add some cones, I added a new osg::Cone with the desired parameters. Unfortunatelly, the cone didn't appeared where it was suppossed to.
I clean up the code and I copy here a snipset of the code I used and a
screenshot.
This code adds a Cone and a Box.
Both objects with the same origin. The box is only for reference (it
represents the XY plane at z=0).
As you can see in the attached screenshot, the cone is displaced 25% below
the XY plane (100 units). Its size is 400.
I was expected to that the bottom of the cone at z=0. Or, as in other API's,
the center of the cone at z=0.
Any ideas? is it a bug?
Thanks
=============== CODE =======================
ViewerQT* viewerWindow = new ViewerQT;
//create a group and add the loaded model => terrain
osg::ref_ptr<osg::Group> groupRoot = new osg::Group;
//Add the Cone
osg::Geode* geo = new osg::Geode();
geo->addDrawable(new osg::ShapeDrawable(new
osg::Cone(osg::Vec3(0,0,0), 50, 400)));
geo->addDrawable(new osg::ShapeDrawable(new osg::Box(
osg::Vec3(0,0,0) , 100, 100, 0.05f )));
groupRoot->addChild ( geo);
//set camera and set the root node.
viewerWindow->setCameraManipulator(new osgGA::TrackballManipulator);
osg::ref_ptr<osgText::Text> updateText = new osgText::Text;
// add the HUD subgraph.
groupRoot->addChild(*createHUD*(updateText.get()));
viewerWindow->addEventHandler(new *PickHandler*(updateText.get()));
viewerWindow->setSceneData(groupRoot.get());
