Introduction In the previous article we gave an overview of the process for creating a custom aspect and showed how to create (most of) the front end functionality. In this article we shall continue building our custom aspect by implementing the corresponding backend types, registering the types and setting up communication from the frontend to […]
Introduction Qt 3D has a flexible and extensible architecture that allows us to easily add our own new functionality to it without disrupting the existing features. The functionality of Qt 3D is divided among so-called aspects, each of which encapsulates a particular subject domain such as rendering, input, or animation. This short series of articles […]

It’s usually said “only improve performance where a profiler tells you to“. I don’t completely agree. Take a big C++ library like Qt: can you profile all classes and all code paths ? It would take a couple of years to accomplish and analyse the results. It’s expensive: It usually only happens if the speed-up […]
