[enhancement] removing qglviewer::Vec in favour of QVector3D

[taiya]

QGLViewer defines yet-another-vector-type. Couldn't you just use the QVector3D that now ships with Qt5? Especially the OpenGL4 API for Qt accepts natively QVector3D, etc... Because of this incongruence my code is scattered with usages of this function:

#include <QVector3D>
namespace qt{
    inline QVector3D tr(const qglviewer::Vec& v){ 
        return QVector3D(v.x, v.y, v.z); 
    }
}

Yes, that's scheduled. QQuaternion and QMatrix4x4 could also be used, simplifying the code.

However,

• Qt5 is not so widely adopted, and I don't want to maintain an other version for Qt4
• This kind of refactoring, including all the examples, requires some time, and it's hard to find.

Also on the list is a switch to a more recent OpenGL rendering. That's the roadmap for libQGL version 3.

Hi Gilles, great, so perhaps label these kind of stuff as "enhancements" in github, so I avoid creating duplicates :) Unfortunately OpenGL4 in Qt4 was a pain, and that's why I am using Qt5.

Do you have any expected release date for version 3? Perhaps it's just simpler to just do OpenGL4/Qt5 and drop back-compatibility. It's a bold move, but often appreciated.

[GillesDebunne]

No time frame. These are just ideas at the moment.

Version 3 would also target a more recent openGL and would be using shaders. Any other ideas (mostly of things to remove) is welcome.
