[Interest] Trouble rendering a single scene into multiple QOpenGLWidgets

2017-08-17 Thread Jonathan Poncelet
Hello all, I was wondering whether anyone might be able to give me any pointers regarding how to make multiple QOpenGLWidgets play nicely with a single 3D scene, as I'm fast running out of ideas. Firstly, a little context: in my application, which is currently completely single-threaded, I have

Hello all, I’m currently using Qt3D 1.0 - I intend to upgrade to 2.0 ASAP but at this point, for the purposes of finishing my university project, I need to stick with the previous version. I have a few questions about ownership of various objects passed to QGLSceneNode. For example, setTransfo

Hello all, Could anyone explain to me exactly how the Qt3D library is to be used with pre-built Qt 5.2.1 for Windows? The page  https://qt-project.org/wiki/Introduction-to-Qt3D says that it's part of Qt5 but I can't seem to find it anywhere, unless it's exclusive to non-pre-built versions. I'd
