I have a problem with Viewer:computeIntersections for nodes below a subgraph
rendering camera that doesn't have the ABSOLUTE_RF reference frame. In fact,
computeIntersections results are exactly as though an ABSOLUTE_RF has been
set on the camera, even though it has not. The code below creates a simple
scene the exhibits the problem. I used this in the osgpick example to show
computed intersections.
Is this a bug, or is this to be expected? If it is to be expected, how can I
get picking to work for nodes below my post render camera?
Chris.
osg::Group* group = new osg::Group();
osg::Geode* sphere = new osg::Geode();
sphere->setName("Sphere");
sphere->addDrawable(new osg::ShapeDrawable(new osg::Sphere()));
osg::Geode* cube = new osg::Geode();
cube->setName("Cube");
cube->addDrawable(new osg::ShapeDrawable(new osg::Box()));
osg::Camera* camera = new osg::Camera();
camera->setRenderOrder(osg::Camera::POST_RENDER);
camera->setClearMask(GL_DEPTH_BUFFER_BIT);
//camera->setReferenceFrame(osg::Transform::ABSOLUTE_RF);
group->addChild(sphere);
group->addChild(camera);
camera->addChild(cube);
