What you are looking for is rendering to framebuffer, this make a custom 
painting for the item (all Qml Item are OpenGL based for now under the hood). 
All you need to do is a view Qml Item that render your framebuffer as a texture 
(your Qml viewport of some sort). What you just link is putting the texture to 
the item. All you need is render your 3D to framebuffer, something more like 
this: http://doc.qt.io/qt-5/qtcanvas3d-framebuffer-example.html


This should help get started. I hope your rendering can do it into a 
framebuffer which can be sized as your Item and then apply that framebuffer to 
your Item painting/rendering.

You might also want to give a look to Qt 3D object structure (this might give 
you some hint how to create your own Viewport/GlViewer objects and interface.

My clients actually required that we used an UI that wasn't native and that had 
a web 2.0 look, so the Qml/C++/OpenGL combination was a godsend.

This is exactly what I was looking for, I don't really need native look & feel 
Please could you elaborate on the approach you have taken?
did you follow this approach
