[Qt-3d] How to perform Picking in Qt3D

[Mülner, Helmut]

Picking in QtQuick3D is done by setting the property "picking" of the Viewport element to true.
(see http://doc.qt.nokia.com/qt-quick3d-snapshot/qml-viewport.html).

Demos where picking is set to true, are: robobounce and teaservice.

With Qt3D you use QGLView::registerObject and QGLView::objectForPoint .
