http://labs.qt.nokia.com/2012/04/11/qt-3d-and-qt5-qt4-news-and-releases/Well its taken 3+ years for Qt 3D to be an overnight success, buthere it is: we are now part of Qt5 and we’ll be front and centre in theexciting picture that will be powering a new generation of QML enhancedapps on a whole range of platforms. As a
Qt5 Essential Qt 3D will be running on all those
supported Qt5 platformsproviding OpenGL accelerated 3D content defined in QML. Its great newsfor us in the team, and good news for those of you using Qt 3D orplanning on using it for your projects.
If you’re a Qt 3D fan and have been following the project for a whileyou’ll know that as a labs project we had to do our own releases,carefully making sure that packages we created matched the currentsupported versions of Qt 4. We have in the past released easy-to-usepackages for Symbian^3, N900 and the N9 platforms, as well as forWindows desktop; and supported
Linux and Mac with source packages. Wegot great feedback from those package releases, and saw some interestingprojects built on Qt 3D.
As part of Qt5 the
SDK team and release program will
make Qt 3Davailable through official Qt5 release activities. This will free us upto spend more time on performance, bug-fixing and best of all thefeatures that we’ve been asked for. This is fantastic news for us sincepackaging consumed quite a bit of our resources, and now we can focusthat on improving Qt 3D.
Before we move away from Labs status we are making one more Qt 3Dlabs release: and this is it. This follows our Qt 3D TP1 and TP2releases with a 1.0 release as part of our Qt 4.x programme. In thisrelease are a number of important bug fixes, some new stuff likethreaded texture and model loading, and the new Qt 3D Asset Viewer,which allows you to visually configure the models you
load into your Qt3D applications.
Today we announce our Qt 3D 1.0 for Qt 4.8.1 with only a small amount of fanfare: this will be our last
4.x major version release.
For
Windows folks, you’ll need the Qt 4.8.1 Windows MSVC release which is
available from the Qt downloads page.
The documentation is also available
on-line on the Qt project site.
For N9 developers we no longer create a package. The
publicly available Qt SDKcan build these packages for you from our source download using the Qt4.7.x Harmattan support, that is built right in to your SDK. Justfollow the special
N9 instructions in our build documentation.For Symbian likewise you will need to create your own packages. Forfolks using a
MinGW based Qt on Windows, you will need to use the sourcepackage also.
Why are we
not supplying N9 or Symbian packages for Qt 3D 1.0 againstQt 4.x? Since Qt 3D 1.0 for 4.x is a labs project, our previous devicepackages were not official
Nokia system packages, and just functionedas a convenience to the developer. This is why we’re asking that youcreate your own packages to underscore the fact that Nokia does notsupply Qt 3D system packages as part of Qt 4.x, and you’ll need to doyour own work to include any Qt 3D functionality in your device apps.Apologies for this, but its the way it is for our 4.x labs statusprogramme. Qt 3D team remains available on IRC and via our email lists(see below) to support you as far as possible when including Qt 3D inyour apps, but unfortunately for Qt 4.x we cannot supply Nokia systempackages for these platforms.
What about Qt5? That is where the excitement lies, with a vastlyimproved QML rendering engine, which has the benefit for Qt 3D ofguaranteed OpenGL support. If you have QML2 then you have OpenGL andthat means Qt 3D is ready to go on any Qt5 platform. We’d love you totry out Qt 3D on Qt5 – go and check out the
Qt5 Alpha release which has just been announced, and tell us what you think. If you want to try out the bleeding edge, you can also get
Qt 3D in Qt5 by building from Git.
