Is there any possibility to display and or to draw items in 3D in Qt without using the OpenGL part of Qt? For each of the items I want to visualize I can calculate the x, y and z coordinates of all the points that the item contains.

I would like to have something like QGraphicsView only in 3d if that is possible.

There is Qt3D available but it will not let you avoid using OpenGL.
