Hi guys!
Recently I tried to create a simple 3D application with Qt basing on "basic shapes" example from Qt examples directory.
I figured out the lack of documentation for this module in Assistant.
A lot of classes have doc like this: http://prntscr.com/j1oox7
just name, list of members, and no general description what it is and how to use it.

Question: are there any guides with detailed descriptions for Qt3D?
Can you recommend a short introduction into 3D math (quaternions/rotations/transformations) that could be applied for Qt3D without months of learning?
