Solving cancer is probably the biggest mystery that we see unravel in our life. This is a complex one because cancer is not a single disease, there are a myriad of aspects that need to be uncovered. Qi (Quantitive Imaging Systems) images biopsies from patients and then labels individual cells with over a hundred biomarkers. […]

When Competence Center ISOBUS (CCI) decided to bring their terminal up-to-date as part of the Group’s strategy to remain top of the field in advanced agritechnical innovation, they asked KDAB to help. The user interface in the operator’s cab displays multiple applications. It can control complex agricultural tools, receive and display complex reports and much […]

An existing code base can be a great asset, but it can also be a liability. Technical debt tends to build up over time, eventually reaching the point where something needs to be done. KDAB has unique experience in migrations as well as specialized tools and in-depth knowledge from migration projects in different industries with […]

QtQuick is a popular choice for creating HMIs for embedded devices. The hardware on these devices is often constrained and less performant than their desktop equivalents, this requires extra care from software developers in delivering a fluid user experience. KDAB is regularly involved in improving the performance of QtQuick HMIs on such devices for their […]

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. […]

On December 1st, KDAB’s Kévin Ottens and David Faure co-hosted a one day Meet Qt in Lyons, with The Qt Company and Witekio. The event was booked out with 50 people attending, confirming the growing community of Qt users in France. Participants were given plenty of opportunities for questions throughout the day and much appreciated […]

Having 3D scenes in your application is becoming a clear trend and is likely to become even more important in the future with the growth of Virtual Reality and Augmented Reality. So far Qt was allowing you to integrate with Open GL fairly easily, but managing the rendering code itself was still a very challenging […]

Design, Technical Excellence and Superb User Experience Why does a tipper truck need an app? Meiller is the leading manufacturer of tippers in Europe. KDAB software developers and UI/UX designers worked with Meiller to create a mobile app that interacts with embedded hardware on the truck, allowing drivers to diagnose and fix problems - even […]

We had a huge amount of fun at QtCon in Berlin.

Some of you may know that Qt 3D is going strong almost entirely due to the work of the KDAB team, led by Dr. Sean Harmer and Paul Lemire. You can read all about its near demise and ultimate rescue here - it’s quite a story, and started with the release of Qt 4. Now […]

Demonstrates the use of Qt 3D using the QML API to create a high quality, animated 3D visualisation application. The demo shows Qt 3D’s ability to use custom shaders that implement a metal-roughness physics based rendering (PBR) pipeline. The PBR shaders coupled with specially crafted material textures and environment maps gives a very realistic simulation […]

mPro (formerly Migari) is a comprehensive software system for the management, monitoring and automation of precision measurement systems in the context of quality control. It can integrate a wide variety of measurement hardware and buses and is programmable and extensible by the integrator and end user. This is necessary as such systems are generally custom […]

Abstract: “QtQuick in Qt5 uses OpenGL to deliver fluid, performant visuals, and an internal scene-graph structure to permit threaded rendering, decoupling the main application thread from interacting directly with the graphics driver. For developers work with an existing rendering or visualisation technology, this presents both an opportunity but also problems; QtQuick offers a compelling, modern […]

by Sean Harmer of KDAB Back in the days when Qt was owned by Nokia, a development team in Brisbane had the idea of making it easy to incorporate 3D content into Qt applications. This happened around the time of the introduction of the QML language and technology stack, and so it was only natural […]
