It appears there are two different Scene3D elements in QML, one from QtDataVisualization (documented here, header file here), and one from QtQuick.Scene3D (used in this example, header file here). They have different properties. However the Qt3D Scene3D example links to the documentation for the Scene3D from QtDataVisualization, which is the wrong QML type. I cannot find a documentation page for the Qt3D Scene3D type. This must be wrong, right?
