Recommend a good starting point for QtQuick3D and Physics

Question

Hi,

I have searched for a long time on google and I can't seem to find good information regarding using a physics library with QtQuick3D. I know people have done it many years before, but my guess is that all of this is outdated.

I have found "PyBullet/Bullet" physics library but I don't really know how to interface it with QtQuick3D, or QT itself.
My interests are in heightmaps and vehicles/objects. I have already done some heightmap with QtDataVisualization.

Anybody has a suggestion of where/how to start learning, or any tutorial on this? I have done many QT projects before and I'm familiar with the basics of QT.

I would like to use QT Design Studio if possible. (I know, there's a lot of work!)
