Subject: Re: [Development] Moving math3d classes from GUI to CORE
> After some thinking, I pretty much agree with Laszlo. QVectorND, QMatrix4x4 and most other classes in math3d are really tuned towards graphics, and thus make little sense in Qt Core. So +1 for keeping them where they are and in addition a +1 for deprecating QGenericMatrix.
> But I think that in this case would make sense to add the QMatrix3x3 class now instead of returning a std::array. We could keep the class fairly minimal in 5.15 so that it in practice is not much more than a wrapper around float. But we’d have the right type then and can add API for it as needed for Qt 6.
I've just created https://bugreports.qt.io/browse/QTBUG-81655 for this. I list there some issues to be solved / decided, before the work can be started. Please comment.
Thanks and regards
