Hi, Robert
Someday before I asked a question about drag object in OSG and you told
me to see osgmanipulator example. It's great.
I tried to modify it as I want to move one object in the scene but the
whole scene. I tried to do this in addDraggerToScene function:
osg::Node* addDraggerToScene(osg::Node* scene,
osgManipulator::CommandManager* cmdMgr, const std::string& name)
{
scene->getOrCreateStateSet()->setMode(GL_NORMALIZE,
osg::StateAttribute::ON);
osg::Node* selectedObject=FindByName("Teapot01");
osgManipulator::Selection* selection = new osgManipulator::Selection;
selection->addChild(selectedObject);
osgManipulator::Dragger* dragger = createDragger(name);
osg::Group* root = new osg::Group;
root->addChild(dragger);
root->addChild(selection);
root->addChild(createHUD());
float scale = selectedObject->getBound().radius() * 1.6;
dragger->setMatrix(osg::Matrix::scale(scale, scale, scale) *
osg::Matrix::translate(selectedObject->getBound().center()));
cmdMgr->connect(*dragger, *selection);
return root;
}
And here my scene has two objects, one teapot, one box. But when I run
the program, I see only the "Teapot01" which really can drag and move,
but the box is lost!
I don't know how to only move one object in the scene. Please give me
some ideas. Thanks.
