Hello, I'm am finishing an assignment with OSG and I need help with a few bits.
I have finished all the hard stuff it's just the optional stuff that I need to
do now and any help or support would be much appreciated.
This is the code I have used to implement a Trackball Dragger into my program:
osgManipulator::TrackballDragger *pDragger=new
osgManipulator::TrackballDragger();
pDragger->addTransformUpdating(pMatrixTransform);
pDragger->setInitialBound(pSwitch->computeBound());
((osg::Group*)pMatrixTransform->getParent(0))->addChild(pDragger);
pDragger->setupDefaultGeometry();
//float scale = pDragger->getBound().radius() * 1.6;
//pDragger->setMatrix(osg::Matrix::scale(scale, scale,
scale)*osg::Matrix::translate(pDragger->getBound().center(),
pDragger->getBound().center(), pDragger->getBound().center()));
pDragger->setHandleEvents(true);
pDragger->setActivationModKeyMask(osgGA::GUIEventAdapter::MODKEY_CTRL);
I have implemented a Trackball Dragger to interact with a robot I have created
but want to know how I can select the robot I have made using the mouse. If
this is overly complicated, don't worry about it.
Also, how do I make it so that the trackball dragger geometry is only visible
when holding the CTRL key?
Again any help would be very much appreciated.
