In the previous two blogs in this series I showed how solving an apparently simple problem about loading a lot of data into RAM using mmap() also turned out to require a solution that improved CPU use across cores. In this blog, I’ll show how we dealt with the bottleneck problems that ensued, and finally, […]

Stay up-to-date and get inspiration from KDAB’s expert insights into Qt, C++ and OpenGL development.
Our engineers and designers share cutting-edge technology news and ideas with regard to Qt, QML, Qt on Android, OpenGL, Qt 3D, Vulkan, Scalable UIs and more embedded, mobile and desktop-related topics.
In my last post, I went through a method of creating a simulated reflection with a simple scene. This time I’d like to take the technique and apply it to something a bit more realistic. I have a model of a car that I’d like to show off in KUESA™, and as we know, KUESA […]
KUESA™ is a Qt module designed to load, render and manipulate glTF 2.0 models in applications using Qt 3D. Kuesa provides a C++ and a QML API which makes it easy to do things like triggering animations contained in the glTF files, finding camera details defined by the designer, etc. It is a great tool so […]
We have released version 2.11.0 of our Qt application monitoring tool GammaRay. GammaRay allows you to observe behavior and data structures of Qt code inside your program live at runtime. GammaRay 2.11 comes with a new inspection tool for Qt’s event handling, providing even more insights into the inner working of your application. Besides looking […]
In Part 1 of this series we solved the problem of using mmap() to load large set of data into RAM all at once. The catch was that it still took too long. In this blog, I describe how we solve this.
KDAB is sharing the Qt booth at SIGGRAPH in Los Angeles. We’ll be showing some of our profiling and debugging tools as well as our latest QiTissue demo, a desktop Application developed for Quantitative Imaging Systems (Qi) to help cancer researchers efficiently handle gigabytes of data (see more about that here), We’ll also give a preview […]
Neither KUESA or Qt 3D Studio will give free reflections. If you know about 3D, you know it requires ray tracing software, not OpenGL. So, I wondered if there would be an easy way to create this effect.
We got a call from a bioinformatics group at a European university. The problem appeared simple, how to usemmap() to load a large data set into RAM all at once. OK, no problem I thought...
CppCon is the annual, week-long face-to-face gathering for the entire C++ community – the biggest C++ event in the world. This year, for the first time, CppCon takes place in the stunning Gaylord Rockies Hotel and Convention Center in Aurora, Colorado, very near Denver International Airport. KDAB is a Bronze sponsor this year, and Milian Wolff is […]
KDAB has released a new version of KDSoap. This is version 1.8.0 and comes more than one year since the last release (1.7.0). KDSoap is a tool for creating client applications for web services without the need for any further component such as a dedicated web server. KDSoap lets you interact with applications which have […]
