3D scenes in applications are becoming increasingly important with VR/AR growth. While Qt allowed OpenGL integration, managing rendering code remained challenging. Qt 5.7's new Qt 3D module eases 3D scene creation through its API, but functions as a complete simulation engine capable of much more than just 3D rendering.

Using OpenGL code with Qt is a long love story... long enough that there might be skeletons in the closet. Indeed, the OpenGL code of your Qt application could have been written before the modernization of the OpenGL API to exploit better GPUs. In this talk, we will walk through a technique to help refactor your old OpenGL code in the safest way possible and get it ready for the 21st century.
