Sometimes data visualization might call for more than a graph – you need to visualize complex data, such as that generated by city lighting, in three dimensions to get the full effect. KDAB decided to put together a showcase for the Qt World Summit that allowed us to demonstrate Qt 3D’s capabilities as a performant […]

What is Qt 3D? Integrating Qt 3D into user interfaces
Qt now provides a new module named Qt 3D. In this very short talk Giuseppe D’Angelo introduces some of the design ideas behind Qt 3D, discuss its use cases, and shows how simple it is to get 3D content in an application when using Qt 3D APIs.
Qt 3D Animation Easter Teaser Using Blender and Qt 3D in Qt 5.9 to create, texture, and animate a model
As an Easter treat here is a quick taster of some of the animation goodies coming to Qt 3D along with Qt 5.9. In this post we will briefly outline the steps needed to create a simple Qt 3D application and the assets it uses to produce this little animation:
Safety critical drawing with OpenGL SC The main sticking points when migrating OpenGL ES software to functionally safe OpenGL SC
Bringing software into a safety critical environment can be tricky, especially when using the complex APIs needed for modern 3D graphics. That’s what makes OpenGL SC (Safety Critical) so important: it bridges the gap between beautiful displays and functional safety, while trying to remain as close to existing embedded standards that we all know and love. OpenGL SC will only […]
KDAB contributions to Qt 5.8
Qt 5.8 has just been released! Another great release of Qt, made possible by thousands of commits by over a hundred different contributors: And here we are again, with the usual showcase of the most outstanding contributions to Qt 5.8 developed by KDAB engineers. In no particular order: Qt 3D Qt 3D continues to receive […]
GammaRay 2.7.0 Released
We have released version 2.7 of our Qt application introspection tool GammaRay. GammaRay allows you to observe the behavior and data structures of Qt code inside your program live at runtime. Here are a few of the highlights of this release: The new Qt 3D geometry inspector allows you to look at a wireframe rendering of entity geometries, […]
Integrating OpenGL with Qt Quick 2 applications (part 2) Implementing overlays and underlays with the Qt Quick 2 renderer
In the last blog post we gave a very high level introduction to the Qt Quick 2 renderer. We also showed how various signals are emitted by the renderer during the synchronization and rendering steps. In this blog post we’re going to discuss those signals and show how they can be used to implement overlays […]
QtCon Videos On-line
We’re delighted all the QtCon talks have now been released, thanks to the hard work of the folks at KDE. Many KDABians attended QtCon and contributed to the unique new Qt event we co-created in Berlin, September 2016, along with Qt Contributors, KDE Akademy, VideoLan and FSFE. KDAB funded the event upfront and was Gold sponsor at QtCon […]
Integrating OpenGL with Qt Quick 2 applications Part 1
This talk will introduce you to various effective strategies of drawing raw OpenGL content inside a Qt Quick 2 scene. After a brief introduction to how the Qt Quick 2 renderer works, we will see the APIs in Qt 5.6 that allow us to integrate existing OpenGL code and QML. One of the foundation pillars […]
Writing custom Qt Quick components using OpenGL Kevin Funk
Qt Quick and QML provide an easy way to rapidly develop customized, reusable components entirely within QML. As these components grow in complexity, performance and maintainability often suffer, a drawback that is especially noticeable on low-powered embedded and mobile devices. In addition, some specialized components simply cannot be implemented by combining existing Qt Quick items […]
