The latest version of Qt, 5.10, has released today. While many developers will likely stick on the 5.9 branch for long-term support, 5.10 brings several flashy features to the C++ framework.
The headline: Qt 3D Studio is, also, now released.
Last year, NVIDIA donated their DRIVE Design Studio to The Qt Company so developers, both commercial and open-source, can use a WYSIWYG editor for 3D UI design. I have not had a chance to play around with it yet, but it looks a little bit like a Flash Professional-style authoring tool that outputs a 3D UI. One downside, however, is that it looks like the runtime is not licensed under LGPL, but rather GPL or Commercial. This seems like it cannot be used with commercial software unless you purchase the license, although I could be reading that wrong. (GPL-compliant open-source software is fine, though.)
The rest of the update is interesting, too. One noteworthy feature is Qt WebGL QPA. The Qt Company showed it off on a smart TV web browser, but it could provide a new way to look at the native vs web argument. They also made a bunch of changes to Qt 3D and the other modules.
If you’re interested, check out their blog post. I should note that the Qt website is kind-of difficult to navigate – they really want to sell you a license – but the open-source stuff is in there, too.
