We also offer a wealth of new videos for your learning delight, from our Qt and 3D expert developers and designers, and of course, Event News.

A 3D Block Building Game in QML

by Christoph Sterz

During his “paid to play” time at KDAB, Christoph created a novel way to learn more about Qt Quick Rendering Engine, by creating 3D graphics, not unlike the ones you see in Minecraft. How did he do it?

KDSingleApplication

a class for single-instance policy applications

by Giuseppe D’Angelo

Single-instance policy refers to those applications that want to spawn a unique instance for a given user session. Even when launched multiple times, such applications will not spawn a number of separate instances. Instead, the existing instance will be notified, somehow, and some action will be taken by that instance. Typically, its window will be shown (if hidden) and raised to the foreground.

KDSingleApplication is one of KDAB’s utility classes. You can find out more about (and download) KDAB’s eclectic mix of developer tools, libraries and utilities, collectively described as KDToolbox, here…

KDDockWidgets 1.3 released

QtQuick and PySide6 support, and more minor fixes

KDDockWidgets is a framework for custom-tailored docking systems in Qt.

The main highlights for this release are PySide6 and experimental QtQuick support.

The QtQuick backend isn’t production ready, but you can already build with -DKDDockWidgets_QTQUICK=ON, run the examples under examples/qtquick/dockwidgets/ and start reporting issues. There are a lot of new features and bug fixes too.

Kuesa 1.3 released

The Kuesa 3D Studio 1.3 release now supports Qt 6 and rendering on top of Qt RHI (Metal, Vulkan, DirectX, OpenGL). The API has been simplified, making it easier for developers to integrate in applications. It now provides instanced rendering support as well as multi viewport and camera support.

This release also brings full integration of Maya, making it even easier for designers to keep control of the WYSIWYG image in the designer-developer workflow.

Kuesa for Designers by Designers

– Video

In addition to the new short info-videos for designers and developers mentioned above, Nuno Pinheiro and Kirsi Sutherland have made a new 3-part series specifically for designers by designers.

Part One is now released ==>

This 3-part series shows how our designers work with KUESA daily. The scene used as the example is a traditional 3D cube over a simple plane with great looking metallic reflections and a cube reflection on the plane. It is done using only QML, 2D tricks and effects and KUESA Iro materials.
