    Qt3D - what can I say about it?

      A few months ago I embarked on a Masters project in visualisation. At the suggestion of my supervising lecturer I adopted Qt as a platform to work on. On further investigation I discovered Qt3D and took the chance that I could fast track some of my work with things like QGLView, QGLSceneNode, etc. so I could concentrate on the meat of my project and the visualisations I was trying to achieve.

      I know there was a risk using Qt3D given it's age - only available since 2009. What I didn't realise at the time was the work from Qt4.8 to 5.0 ground to a halt on Qt3D and I have seen very little traffic on forums and little or no response to topics I raised. I further complicated my choice I think by choosing the Mac OS as my development platform - but then again - QT is cross platform, right?

      So, I achieved some of my basic project goals, but frequently ran into basic Qt3D / openGL issues which by any text book should work. I'm no expert on openGL but it appears to me, I may have been better off developing using glut / windows / openGL and not bothering with Qt and Qt3D.

      Long way of asking the question: What is the future of Qt3d - really? I've read it will start evolving again after Qt 5.0 is released... so has any work started? It seems to me with such a rich and flexible platform like Qt, it is a shame to leave 3D out in the cold...

        Hi,

        I'm sorry to hear that you've face an uphill battle with Qt 3D. -Unfortunately, there isn't much attention given to it at the moment. Time and manpower are limited, even with Digia's commercial backing, and other things have been given higher priority. Here's a list of the most recent patches merged into the module: https://codereview.qt-project.org/#q,status:merged+project:qt/qt3d,n,z- EDIT: Wrong info, sorry

        If you want to talk to Qt's engineers themselves, subscribe to and post to the "Development mailing list":http://lists.qt-project.org/mailman/listinfo/development

          The existing Qt3D is being rewritten at present to address many of the shortcomings of the current implementation. We are making good progress now and hope to push to a public repo in the near future. I posted about our outlines for a future Qt3D on the mailing list "here":http://lists.qt-project.org/pipermail/development/2013-February/009853.html.

              We're slowly getting there but it's non-trivial to make it extensible for what we want to add in the future.

                Hi,
                Nice to hear you are making progress on Qt3D. Are you rather optimistic or pessimistic regarding inclusion/usability in Qt5.2 ?
                Thanks.

                  We're hoping for a tech preview with 5.2.
