by Timo Buske | KDAB, in collaboration with Schneider Digital, developed an automated approach to simplify 3D stereo visualization — eliminating the need for manual configuration. By dynamically calculating key parameters like focal distance, pop-out, field of view, and camera separation, users can enjoy an immersive 3D experience right out of the box. The open-source stereo demonstrator supports both OpenGL and Vulkan. Read more. |

Several KDAB tools have been updated in the past weeks. Here you can find an overview about them. GammaRay 3.2.0 GammaRay is a software introspection tool for Qt applications developed by KDAB. The new version GammaRay 3.2.0 brings improved support for Qt up to version 6.9, build fixes for newer Windows SDKs, and better UX on small window sizes. This release also adds FreeBSD support and streamlines packaging by offloading KDStateMachineEditor binaries.
KDDockWidgets 2.2.4 KDDockWidgets is a Qt dock widget library written by KDAB, suitable for replacing QDockWidget and implementing advanced functionalities missing in Qt. KDDockWidgets 2.2.4 addresses a crash issue related to using QAction to float tabs, improving overall stability. KDStateMachineEditor 2.1.0 The KDAB State Machine Editor Library is a framework designed to simplify the creation of advanced graphical user interfaces and tools for editing state machines. It generates output in metacode or QML, which can be integrated into broader Qt or QtQuick projects. KDStateMachineEditor 2.1.0 now defaults to Qt 6, with an option to revert to Qt 5 via CMake for compatibility. This release also updates the Graphviz dependency to version 12.2.1 and includes build fixes for Qt 6.9. |
