[QT C++] Qt3DCore : Entity to Map coordiates ?

[Born0x02Code]

Hi everyone,

I want to convert a 3D object (custom loaded .obj / .stl to a QMesh why not after transform (QTransform)) into a 3D X Y Z MAP, to extract lines, arcs, circles and list of points of the surface of the loaded object.
Is there any way to do it only with qt component (without any extarnal library) and without QML?

The purpose of my question is to play with these coordinates by adding or removing points automatically and send it to a custom motion controller.

Thank you in advance.
