Re: [osg-users] Implementation of movement, rotation of scale

Hi, i finded code, but in this function is failed why?


Code:

osg::Node* addDraggerToScene(osg::Node* scene, const std::string& name)
{
scene->getOrCreateStateSet()->setMode(GL_NORMALIZE, 
osg::StateAttribute::ON);

osg::MatrixTransform* selection = new osg::MatrixTransform;
selection->addChild(scene);

osgManipulator::Dragger* dragger = createDragger(name);


osg::Group* root = new osg::Group;
root->addChild(dragger);
root->addChild(selection);

float scale = scene->getBound().radius() * 1.6;
dragger->setMatrix(osg::Matrix::scale(scale, scale, scale) *
osg::Matrix::translate(scene->getBound().center()));

osgManipulator::GridConstraint *con = new 
osgManipulator::GridConstraint(*selection, osg::Vec3(0, 0, 0), osg::Vec3(30, 
30, 30));
osg::ref_ptr m_pManipulator = new 
osgManipulator::TabBoxDragger;
m_pManipulator->addConstraint(con);

dragger->addConstraint(con);
dragger->addTransformUpdating(selection);

// we want the dragger to handle it's own events automatically
dragger->setHandleEvents(true);

// if we don't set an activation key or mod mask then any mouse click on
// the dragger will activate it, however if do define either of 
ActivationModKeyMask or
// and ActivationKeyEvent then you'll have to press either than mod key 
or the specified key to
// be able to activate the dragger when you mouse click on it.  Please 
note the follow allows
// activation if either the ctrl key or the 'a' key is pressed and held 
down.
dragger->setActivationModKeyMask(osgGA::GUIEventAdapter::MODKEY_CTRL);
dragger->setActivationKeyEvent('a');

return root;
}



after RETURN failde:(

Thank you!

2019-05-30 Thread Maxim Senin 
Hi, I want to move, rotate and scale the object with the help of auxiliary 
axes, so as done in the blendar, are there any libraries or code?
